[Abstract]:In the face of the highly information-based trend of war, radar countermeasures put forward higher requirements for intelligent jamming decision systems. The interference decision must be based on the interference profit matrix, but the acquisition of the interference profit matrix lacks accuracy and persuasion, so it is difficult to guide the actual operation. Aiming at the problems faced by intelligent jamming decision system, this paper analyzes and studies the model building of electronic countermeasure strategy. Firstly, the principle of antenna anti-jamming, transmitter anti-jamming, receiver anti-jamming and signal processing anti-jamming are analyzed. The anti-jamming techniques in radar signal processing system are mainly studied, including pulse compression, pulse accumulation, clutter cancellation and Doppler filter bank. Taking the input signal as a linear frequency modulation signal as an example, the process is simulated. The application scope of all kinds of anti-resistance technology is summarized. Secondly, this paper introduces the noise modulation jamming in the radar countermeasure technology, and simulates the signal form of the noise modulation jamming. The measurement principles and methods of ranging, angle and velocity-measuring radar are introduced, and the corresponding jamming patterns of these principles and methods are analyzed. The jamming patterns of range, angle and speed deception are simulated, and the applicable range of radar countermeasure technology is summarized. Finally, this paper describes the measurement criteria of the effects of shaded jamming and deceptive jamming, and analyzes and deduces the effects of shaded jamming on RF noise, noise amplitude modulation interference, noise frequency modulation interference, noise phase modulation interference through pulse compression and pulse accumulation. Clutter cancellation, Doppler filter banks and other signal processing methods before and after the change of dry signal ratio. According to the deceptive jamming patterns of ranging, angle and direction finding, the factors affecting the deceptive probability of radar are analyzed, and the cross-jamming effects of some deceptive jamming are discussed. The process of covering jamming is simulated by radar signal processing, and the variation curve of dry signal ratio and the detection probability curve are drawn. The simulation results show that the degree of interference suppression by the anti-jamming method in signal processing is quantifiable. The quantization value provides an important basis for the setting of interference power.
