摘要
本文主要针对反舰导弹末制导雷达极化抗干扰试验需求,开展阵列式射频仿真试验系统可变极化模拟方法研究。提出了一种目标全极化回波模拟方法,该方法充分考虑目标运动对其极化特性影响,准确描述导弹、飞机等目标高速运动状态下的极化散射特性。根据该方法,采用Simulink进行了典型舰船目标全极化回波仿真,仿真结果表明水平\垂直极化通道回波变化规律同实测数据变化规律保持一致,说明该方法的正确性。研究成果可直接应用于靶场装备建设和试验工作中,为装备建设和导引头试验提供理论基础和技术支撑。
Aimed to the request of anti-ship missile terminal guidance radar polarization anti-jamming test,researching on variable polarization simulation method with RF simulation array system.This paper suggested a new method of targets full polarization echoes simulation.It＇s completely considered the inference of moving targets to polarization characteristics,and correctly described targets such as missile and plane polarization scatter characteristics in moving state.According to this method,the full polarimetric echo simulation of a typical ship target is carried out by using Simulink.The simulation results show that the variation of echo of horizontal and vertical polarization channels is consistent with the observed data.The study results can directly applied on equipment building and test work,provided theoretical basis and technical support.
