摘要
针对雷达制导射频半实物仿真试验系统目标回波模拟逼真度问题,分析了传统做法中未考虑雷达天线方向图的目标回波模拟方法的弊端。采取利用雷达天线方向图调制目标回波功率的方法,对仿真试验系统的回波功率控制算法进行改进,实现了更为真实的目标回波功率变化模拟。仿真结果证明,该方法有效解决了末制导雷达半实物仿真试验过程中,特别是在多目标的环境下频繁出现的副瓣跟踪问题,大大提高了射频半实物仿真系统仿真结果的可信度。
Aims at the target echo simulation fidelity issues of Radar-guided radio frequency hardware in the loop simulation test system,the defects of the traditional approach does not take into account antenna pattern of radar echo simulation are analyzed.Target echo power is modulated by the radar antenna pattern and control algorithm of the simulation test system is improved,a more realistic simulation of target echo power change is realized.Simulation results shows that the method effectively solves the side lobes tracking problem during the test,particularly in the multiple targets situation,the credibility of simulation results is greatly improved.
