Modeling And Simulation Of Radar Electronic Jamming

In the modern war, the electronic war is playing a leading and unreplacement role. And the electronic jamming as the important part of the electronic war is the linchpin technology.Jamming signals which are in common use in the electronic war such as noise jamming, deception jamming and chaff jamming are mainly researched in this paper from the theoretical simulation and the design implement, which lay the foundation for radar countermeasure.Active suppression noise jamming such as RF noise jamming, noise amply-modulation jamming, noise frequency-modulation jamming and noise phase-modulation jamming are researched in this paper, the theoretical model and the numeral simulation of the jamming signals are achived, and the influences with different design parameters on radar system are discussed. And, the jamming mechanism, signal generation and digital simulation results for the deception jamming including distance deception, speed deception and distance synchronous speed deception jamming are researched in this paper. Moreover, based on the radar cross section, spectrum, power spectrum and statistical property of chaff jamming, the numeral model of chaff jamming is build with monte-carlo method. And the simulation results show that the model is correct and can be use to imitate chaff jamming.Based on the theoretical analysis and numeral simulation, software design for RF noise jamming, distance deception jamming, speed deception jamming, distance synchronous speed deception jamming and chaff jamming are given, and different jamming modular are packaged and integrated to form a interference modeling control interface, which is convenient for the jamming design and simulation. Moreover, the The theoretical algorithms are implemented on the hardware platform and the real RF jamming signals which can be used in the radar system are formed, which can provide the technology support for the radar jamming equipment design and anti-jamming examination.
