摘要
机载相控阵火控雷达具有射频功率效率高、多功能、高探测与跟踪能力、形成不同形状波束、极高的可靠性等优点。论文根据侦察截获的充分条件,首先分析了侦察截获所要求的侦察接收机系统灵敏度,在此基础上,分别建立重合概率、检测概率以及脉冲丢失概率计算模型,仿真分析了影响各概率的主要因素。仿真结果表明,合理配置侦察接收机、改善信噪比和减小内部信号密度均可提高对机载相控阵火控雷达截获的可靠性,并最终为对其进行有效干扰做好准备。
Airborne phased-array fire-control radar possesses the merits of high efficiency radio frequency, multi-function, high detection and tracking capability, forming beams of different shapes, high reliability, and etc. According to the sufficient condition of reconnaissance interception, the paper firstly analyzes the system sensitivity of reconnaissance receiver needed by reconnaissance interception. On the basis, the models of superposition probability, detection probability and pulse losing probability are built up respectively. Finally, the main factors that affect the probabilities are simulated and analysed. The simulation results indicate that reasonable configuring reconnaissance receiver, improving SNR, and decreasing the signal density of interior can improve the reliability of intercepting airborne phased-array fire-control radar so as to make preparations for efficient jamming.
