首先分析总结理想情况下雷达方程及其相应参数的求取,研究了有源干扰方程、无源干扰方程、接收机噪声方程及其参数的求取,详细推导了频谱系数.在此基础上,给出复杂电磁环境下综合信干比的计算公式,最后利用求出的综合信干比,计算单次扫描雷达的探测概率和自卫距离,并提出仿真中雷达捕获的判断方法.通过将该模型应用于某型仿真系统中的雷达实体探测模块中,证明该模型具有一定的通用性、准确性和简单实用性.
First of all, the radar equation and its corresponding parameters are calculated and analyzed. The interference coefficients of the active interference, the passive interference, the receiver’s noise and their parameters are studied, and the spectral coefficients are deduced in detail. On this basis, The calculation formula of comprehensive signal to interference ratio in complex electromagnetic environment is given, and finally the probing probability and self-defense distance of single sweep radar are calculated by using the integrated signal to interference ratio, and the judgment method of radar acquisition in simulation is proposed. It is proved that the model has certain versatility, accuracy and simple practicability in the radar entity detection module of a certain type of simulation system.
