地对空雷达干扰系统有源无源联合发现概率

摘要

针对目前地对空雷达干扰系统发现概率模型没有考虑有源侦察与无源侦察之间的指示情形,并且计算模型不完整的问题,提出了地对空雷达干扰系统有源无源联合发现概率建模方法.该方法分析了地对空雷达干扰系统的探测规律,在考虑了发现目标的完整过程下推导了有源侦察方位指示成功的概率、有方位指示和无方位指示情形下干扰站系统的发现概率,然后运用概率论思想建立了系统有源无源联合发现概率模型.仿真分析表明,有方位指示下系统的发现概率大于无指示独立探测的情形,并且指示的时刻越早,系统的联合发现概率增长越快.%Aiming at the problem that the current discovery probability model of the ground-to-air radar jam-ming system does not consider the instructions between active reconnaissance and passive reconnaissance,and the calculation model is incomplete.An active and passive jointed discovery probability model of ground-to-air radar jamming systems was put forward in this paper.This method analyzed the detection law of the ground-to-air radar jamming system.Under the complete process of finding the target,the probability of the successful de-tection of the active reconnaissance orientation,the discovery probability of the interfering station system with the azimuth indication or without were established Then,by using the probability theory,the system active and passive joint discovery probability mode was established.The simulation analysis showed that the probability of discovery of the system under azimuth indication was greater than that without indication,and the sooner the time was indicated,the faster the joint discovery probability of the system grew.
