比相单脉冲雷达目标角闪烁建模与仿真

摘要

This paper discusses the modeling approach to represent complex target by multiple discrete point scatters, and presents the angular glint simulation result which is calculated by using phase grads methods. Comparing with the real angle error measured by phase comparison monopulse radar, it shows that there is difference between angular glint and real angle error. Finally we present an angular glint simulation method which uses the signal generated from sum channel and difference channel of phase comparison monopulse radar.%探讨了复杂目标的多点模型建模问题，给出了采用相位梯度法计算模型进行角闪烁仿真的结果，并与比相单脉冲雷达的真实测角偏差进行了比较，指出比相单脉冲雷达所测角同角闪烁存在区别，通过分析二者之间的联系，提出用比相单脉冲雷达和、差通道回波计算角闪烁的方法。
