目标和干扰极化特性的使用提高了雷达制导武器系统的抗干扰能力,目标和干扰极化特性的模拟又是验证极化雷达识别目标和干扰能力的一个重要手段。本研究从极化雷达的测量方式着手,建立极化雷达目标和干扰回波模型,分析不同目标和干扰极化雷达散射截面(Radar cross section,RCS)特性的差异。在此基础上,提出极化特性控制算法,构建极化信号的调制方法,并在实验室构建半实物仿真环境进行了验证和分析。

The use of polarization characteristics of targets and interference improves the anti-jamming ability of Radar Guided Weapon.The simulation of targets/interference polarization characteristics is an important means of verifying the ability of polarized radar identifying targets/interference.By starting with the measurement mode of polarized radar.This paper focuses on establishing the target/interference echo model of polarimetric radar,as well as analyzing the RCS characteristics of different target and interference.Furthermore,the control algorithm of polarization characteristics is proposed,and the modulation method of polarization signal is constructed.At last,it was verified and analyzed in the hardware-in-the-loop simulation environment constructed in the laboratory.
