With the continuous development of communication technology, the role of jammer in the field of wireless communication countermeasures is becoming more and more prominent. In order to improve jamming efficiency and accuracy, the industry is actively integrating a variety of emerging technologies to give the jammer intelligent, adaptive, refined new capabilities.
Artificial Intelligence and Machine Learning
Artificial intelligence and machine learning technologies have injected an intelligent brain into cell jammer, enabling them to independently analyze complex electromagnetic environments, accurately target and optimize jamming strategies. With the help of deep neural network and other algorithms, the jammer can actively recognize the air interface characteristics of different wireless communication systems, modulation and demodulation methods, etc., and adaptively choose the best jamming means.
At the same time, through the continuous learning of historical data, the signal jammer can gradually accumulate experience, predict the possible countermeasures of the opponent, and respond in advance. This kind of artificial intelligence empowerment significantly improves the intelligence level of the jamming process and the ability of precision strikes.
Cognitive radio technology
Cognitive radio enables the jammer to sense the available electromagnetic spectrum resources in real time, automatically select the free frequency band to transmit, and reduce the impact of interference on other communication systems. This intelligent scheduling based on software-defined spectrum significantly improves the efficiency of frequency resource utilization.
At the same time, cognitive radio technology also gives the drone jammer frequency means of flexibility. The jammer can adjust the transmitting frequency independently according to the frequency jump mode of the target communication system, and realize efficient and accurate tracking of it. For future communication environments where spectrum resources are scarce, this technology can ensure the efficient implementation of jamming strategies.
MIMO arrays and beamforming
Using MIMO (Multiple Input Multiple Output) antenna arrays and beam fouling technology, modern jammers are able to concentrate their energy into a specific spatial direction to form a high-gain, high-precision energy beam. This not only greatly improves the jamming distance and effectiveness, but also avoids the jamming radiation to the non-target area.
In addition, the MIMO system combined with the beam fugitive space division multiplexing and multiple reception capabilities, but also makes the wifi blocker can be synchronized for multiple targets to launch complex modulation of the jamming signal, omnidirectional precision strike, completely destroy the opponent’s reception capabilities.
Quantum communication technology
As a disruptive technology for future communication development, quantum communication also brings new opportunities in the field of jamming. The quantum communication system realizes channel transmission through quantum state coding and entanglement physical properties, which can effectively resist interference and avoid eavesdropping. Therefore, new quantum jamming mechanisms are needed to counteract them.
One feasible solution is to utilize artificially created “quantum noise” to suppress the quantum channel and reduce the lifetime of the quantum entangled state to achieve the purpose of interference. By controlling quantum noise and suppressing the characteristics of quantum states, the future quantum interference mechanism is expected to realize precise and seamless suppression of quantum communications.
