With the rapid development of science and technology, electronic warfare has also entered a new era. As a new mode of warfare, electronic warfare has become an important part of modern military combat. In electronic warfare, signal jammers are widely used in enemy communication jamming, radar jamming, and navigation jamming.
1. The principle of the signal jammer
Signal jammers, also known as electronic countermeasure equipment, are one of the important equipment of modern electronic warfare. It achieves the purpose of interfering with enemy communication, reconnaissance and guidance by generating jamming signals that are coherent with enemy communication equipment, radar equipment, and navigation equipment. Its main principle is to cover the enemy’s communication frequency band by generating high-energy electromagnetic signals, so that the enemy’s communication is in a state of chaos, so that the enemy cannot communicate, reconnaissance and guidance normally.
2. Strategic application of signal jammers in electronic warfare
1. For enemy communication jamming
Enemy communication jamming is a common tactical means in electronic warfare. In order to effectively deal with enemy communication interference, signal jammers can play an important role. First of all, it can interfere with the frequency and phase of the enemy’s communication equipment, causing serious distortion of the communication signal, so that the enemy cannot communicate normally. Secondly, the signal jammer can also transmit a large number of jamming signals, causing the receiver of the enemy’s communication equipment to be severely interfered, and unable to receive the signal correctly, which in turn leads to communication interruption or failure to transmit information normally.
2. Against enemy radar jamming
The radar system is an important means for the enemy to conduct reconnaissance and tracking, and jamming the enemy’s radar system is one of the keys to electronic warfare. Signal jammers are uniquely positioned to jam enemy radar systems. First of all, it can emit a large number of jamming signals to interfere with the receiver of the enemy’s radar system, making it unable to correctly receive the radar echo signal, thereby achieving the purpose of interfering with the enemy’s reconnaissance and tracking. Secondly, the signal jammer can also interfere with the operating frequency of the enemy’s radar system by changing the frequency and phase of the jamming signal, making it unable to work normally.
3. For enemy navigation jamming
On the modern battlefield, navigation systems play a vital role in warfare. The enemy’s interference with our navigation system will have a great impact on our combat plan and execution. Signal jammers can disrupt the signal transmission of the enemy’s navigation system by emitting a large number of jamming signals, making it impossible to locate and navigate normally. At the same time, the signal jammer can also interfere with the operating frequency of the enemy’s navigation system by changing the frequency and phase of the jamming signal, making it impossible to locate and navigate accurately.
3. Strategic application of signal jammers in different scenarios
1. Fighter with strong anti-jamming capability
In modern air combat, fighter jets are often the core force of combat. However, with the continuous development of the enemy’s electronic warfare technology, the anti-jamming capability of fighter jets is becoming more and more important. In this case, signal jammers can be applied to fighter jets to improve the survivability and combat effectiveness of fighter jets by interfering with enemy radar and navigation systems.
2. Ships targeting enemy reconnaissance and targeting equipment
In modern naval warfare, enemy reconnaissance and positioning equipment is often one of the enemy’s advantages. In order to deal with this situation, signal jammers can be applied to ships, by interfering with the enemy’s radar system and navigation system, making it impossible to detect and locate normally, thereby improving our concealment and survivability.
3. Ground forces targeting enemy command and communications systems
In modern warfare, the enemy’s command and communication system is an important guarantee for its combat capability. In order to weaken the enemy’s combat capability, signal jammers can be applied to ground troops, by interfering with the enemy’s communication system, making it impossible to conduct normal command and communication, thereby reducing the enemy’s combat effectiveness.
4. The development trend of signal jammers
With the continuous advancement of technology, signal jammers are also constantly developing and innovating. The future development trend of signal jammers will be mainly reflected in the following aspects:
1. Broader band coverage
Future signal jammers will take into account the interference of more communication, radar and navigation frequency bands to meet the needs of modern warfare.
2. Stronger interference ability
Future signal jammers will increase the strength and complexity of jamming signals, making them more difficult for adversaries to detect and overcome.
3. Intelligent control is more convenient
The future signal jammer will use an intelligent control system to make its operation easier and more efficient, and improve battlefield adaptability and practicability.
4. Integrated application of multiple jamming technologies
Future signal jammers will integrate a variety of jamming technologies, such as frequency jamming technology, phase jamming technology and coding jamming technology, to improve the jamming effect.
As an important equipment of electronic warfare, signal jammer has an important strategic application in defensive electronic warfare. By interfering with the enemy’s communication, radar and navigation systems, signal jammers can effectively reduce the enemy’s combat effectiveness and improve our survivability. With the continuous advancement of technology, future signal jammers will be more intelligent, flexible and powerful, making greater contributions to the victory of electronic warfare.
