When people describe the role of the "multiplier" of electronic countermeasures, they usually list the war damage rate when the Second World War and the Vietnam War attacked the aircraft to break through the other air defense system, and prove the electrons with the effect of the electronic countermeasures support. The special role of confrontation. However, such war cases reflect only specific and partial electromagnetic struggles, and the conclusions drawn are often universal in mechanized warfare. In the information warfare, the role of electronic countermeasures is extended to the entire combat system, and its application concept must emphasize the alliance to effectively capture the electromagnetic spectrum advantage that is indispensable for joint operations.
The role of the combat "multiplier" is extended to the entire combat system.
In mechanized warfare, the object of electronic countermeasures is usually a relatively separate single station, radar, even if it is more complicated, it also stays at the level of the radio network and radar network. The electromagnetic activity of such targets poses a local threat only to the specific operations of the other armor, artillery, aviation and other forces. The role of the electronic multi-combat combat "multiplier" naturally supports the form of cooperation, showing the increase in combat effectiveness and survivability of other services. Therefore, for a long time, people have included electronic countermeasures in the field of combat protection.
In the information battlefield, the wide application of electronic information technology seamlessly links information activities such as perception, transmission, sharing and target guidance of land, sea and air space, thus giving the connotation of joint operations integration. At this time, the electronic confrontation should not only continue to carry out targeted and targeted struggles against specific electronic information systems in specific operational actions, but also need to break the integration of the other party's integrated joint combat system, affecting the formation and exertion of its overall operational effectiveness. Improve your overall combat effectiveness. The "multiplier" object of the electronic multi-combat combat "multiplier" naturally extends from one shot to one gun, one machine and one car to the entire combat system.
Therefore, the construction of electronic warfare forces in the information age should continue to strengthen and enhance the ability of electronic warfare support and coordination of various arms and services, while focusing on the growth of the overall combat effectiveness of the joint combat system and building a joint electronic countermeasure capability.
The objective attributes of electronic confrontation put forward special requirements for their joint use
Human beings and all entities of their social activities must survive and move in the physical space of objective existence. The most intuitive of these is the land, sea, and sky geospatial space, which also distinguishes the types of services of the land, sea, and air. However, all social activities of human beings are information-oriented material and energy movements. The moving objects in geospatial space can display their active processes and transient states with intuitive material existence and energy release. However, there is another form of expression in information activities, that is, electromagnetic activities in which human senses are difficult to directly and comprehensively feel. As a special form of material existence, this kind of electromagnetic activity without mass and propagating at the speed of light, on the one hand, fully penetrates into every corner of the land, sea and sky, on the other hand, it can freely exist beyond the constraints of geospatial space. These objective attributes not only provide convenience for the joint use of electronic countermeasures, but also put forward special requirements.
The purpose of joint use of firepower in various services lies in the pursuit of efficiency and cost. For example, for a bunker on a beach position, it can be destroyed by various means such as ground assault, surface fire support, and air fire strike. No matter which means, almost all means are sure to ensure the destruction. Compared with firepower strikes, the combined use of electronic countermeasures is more inevitable. Even for a certain kind of electronic information activities, it is necessary to simultaneously exert force through the electronic countermeasure platforms of land, sea and sky, in order to achieve the corresponding operational objectives. This feature has only appeared during the mechanized war. In the Normandy landing operation, the Allied forces carried out a turbulent "ghost" fleet in the direction of Calais, using both airborne balls, surface dinghy boats equipped with jammers, and aircraft specially equipped with interference corridors. The interference targets were focused on The Germans deployed several warning radars on the French coast. The electronic countermeasures of the joint multi-dimensional space platform attack one or several specific targets of the enemy, so that the electronic countermeasures have the innate joint operational attributes.
The information activities of the informationized battlefield place more emphasis on sharing, complementarity and compoundity, and aim to ensure the effective integration of the various military forces and actions distributed in various geographic spaces. At this time, the electronic information system and related information activities are also inevitably distributed in various dimensional spaces, belonging to various arms and services, serving various combat operations and their various links. Electronic countermeasures must also aim at the enemy joint combat system and strive to undermine the overall operational effectiveness of its joint operations. "Joint fight and fight alliance" has become the basic mode of electronic warfare operations in information warfare.
Electronic countermeasures should be combined with cyber confrontation to compete for information superiority
The so-called network, its physical form is still interconnected cable and electromagnetic waves, which is not fundamentally different from traditional telephone networks and radio networks. However, the reason why the modern meaning of the network far exceeds the telephone network and the radio network is the semantic analysis of the transmitted information. Due to the artificial intelligence intervention of the computer, each network terminal changes the traditional processing flow after manual signal transmission to the automatic analysis while transmitting the signal, and autonomously guides more complicated actions according to the parsed semantics. Rather than saying that the network is named for its composition, it is better to say that the network is named to reflect the networking of human social activities. Therefore, it can be considered that the emergence and application of the network replaces the information processing work of the human brain in human social activities, and partially replaces the subjective role of human beings in objective social activities. With the advancement of artificial intelligence, this trend of socialization and intelligence is more obvious. Information warfare is being driven by signal-driven automation and rapidly moving to the advanced stage of unmanned and intelligent information driven by information content.
So, what is the difference between electronic confrontation and cyber confrontation? The electronic countermeasure detects the electromagnetic signal of the other party, and deceives the other party with a similar signal, or directly uses the noise signal to flood it, while preventing the damage of the other party from such actions, and the information content contained in the signal is not concerned. The network confrontation detection is the relationship and authority of the network connection, which in turn transmits the information containing the consciousness of the other party, misleading the other party's network and its terminal to generate false judgments, thereby causing false behaviors, and preventing the damage of the other party's actions to their own side. As for the signal The form and semantic format must be known.
It can be seen that the advantages and disadvantages of electronic countermeasures and network confrontation are complementary. The combination of the two can cover the complete link of information activities from perception, transmission, processing to effectiveness, and thus achieve full control over the initiative of information activities. The network electromagnetic space has further enhanced the original role of the electromagnetic space. The joint action of the network electromagnetic integration will become the most intense and critical link in the information war.
Therefore, it is impossible to negate or replace electronic confrontation because of the rise of cyber confrontation, nor to hold on to traditional electronic confrontation. The development and application of electronic countermeasures needs to seek new growth points from the perspective of network and power integration.
The confrontation of electronic countermeasures from the information domain to the geographic domain is crucial
Electromagnetic space is the main battlefield of electronic countermeasures. Information based on electromagnetic activity and its activities are the direct targets of electronic countermeasures. However, the effect of electronic countermeasures must be reflected in the geospatial space of land, sea and air, and the ultimate goal of “cross-domain effect†is achieved through the improvement or weakening of the overall operational effectiveness of joint operations. Therefore, the mapping of electronic countermeasures from the information domain to the geographic domain is crucial. Through the electronic countermeasures of "joint fight and joint fight", it is reflected in the joint effect of geospatial power and firepower, which is the only way to win the information war.
For electronic countermeasures, "joint fight" is only the process of forming an electromagnetic sword. "Joint joint" is to determine the target of attack by focusing on the effectiveness of the enemy joint combat system. Without paying attention to the leap from the information domain to the geographic domain, all the games of electronic confrontation in the electromagnetic space have lost their meaning. For the force fire action of the geospatial space of the land, sea and air, the joint meaning is to realize the synergy of the force and firepower, and the joint ties mainly rely on electromagnetic information activities and network information activities. Thus, the overall effectiveness of joint operations, including the operational effectiveness of the information weapon platform, naturally establishes an inseparable connection with electromagnetic information activities. This kind of connection is the conditional basis for the electronic confrontation to defeat the enemy in joint operations. The “cross-domain effect†based on this kind of connection is the essential requirement of the electronic confrontation “joint fight and fightâ€.
Conversely, the force fire action in the geographic domain can also impose tangible physical damage on the electronic information system and the electronic countermeasure equipment platform, which in turn affects the electromagnetic space struggle. Therefore, in the critical stage of joint operations for the right to information, it is also necessary to combine the forces of various geospatial forces to destroy enemy electronic targets such as detection and warning, navigation and positioning, command communication and electronic countermeasures platforms, and to combat enemy electromagnetic activities. The ability to "host" to achieve a reverse "cross-domain". All of this can be found in Comrade Mao Zedong’s "A Long-Term War" in 1938: "We want to seal the eyes and ears of the enemy as much as possible, and make them into scorpions and scorpions. The commander's heart is as chaotic as possible, making them crazy, to fight for their own victory."Coaxial Power D-Sub Solder Cup
Coaxial Power D-Sub Solder Cup Contacts with Mixed or Full Layout
Transmit Radio Frequency Signals
The Coaxial D-Sub have like the Power D-Subr replaced the two rows in a Standard Density connector with a coaxial contact that take up about the same size as the two rows of signal contacts. The Coaxial D-Sub is exactly the same size as the Standard Density connector but instead of example 9 positions of signal pins it has 2 power contacts , or instead of 37 positions of signals it has 8 coaxial contacts.
The Impedance for the coaxial contacts are 50Ω or 75Ω
The Coaxial D-Sub with Mixed Layout mixes both coaxial contacts and signal contacts in the same connector. For example the same size as a 15 position Standard Density D-Sub you can have what we call a 7W2, which means there is 7 contacts where 2 of them are coaxial contacts, which means there are 5 signal contacts, so 5 signals and 2 coaxial. See the Layout in the Tech Specs on the bottom, there are a lot of combinations of the Mixed Layout alternative.
