摘要:

研究了弹载雷达单脉冲前视成像的回波建模方法。通过对单脉冲前视成像原理的分析,设计了弹载雷达运动模型和回波模型两个模块,回波模型中包括扫描过程天线方向图增益计算及回波表达式的分析和构建。通过仿真验证了该建模方法能够有效地获取目标的一维距离像,并测试验证了扫描过程中目标回波幅度变化的正确性,为后续的单脉冲前视成像提供了分析依据。

Abstract:

The echo modeling method of monopulse forward-looking imaging of missileborneradar was studied. By analyzing the principle of monopulse forward-looking imaging,two modules of missile motion model and echo model were designed. The echo modelincluded the calculation of the antenna pattern in the beam scan and the construction of theecho expression. It is verified that the method can effectively obtain the one-dimensionaldistance image of targets through simulation, and the correctness of the target echoamplitude change during scanning is proved by test, which provides an analytical basis forsubsequent monopulse forward-looking imaging.
