宽带雷达动态目标建模及仿真研究

对复杂动态目标进行回波建模是研究目标散射特性，实现雷达跟踪识别动态目标的重要基础。该文利用宽带雷达的高分辨特性，分析了宽带信号照射到运动点目标上的回波信号形式，根据高频区目标总的电磁散射是多散射中心的合成的原理，得出了宽带雷达动态复杂目标的回波模型，并针对冲击雷达信号运用该模型进行回波仿真，获得给定目标在平动及转动情况下的回波仿真信号。仿真结果较好地反映出目标特征，为进一步进行雷达目标的识别提供了理论分析依据。

Modeling and Simulation of Wideband Radar Moving Targets' Echo

It's crucial to study the modeling of wideband radar moving targets' echo in order to detect and trace the moving targets.In this paper,by analysing the electromagnetic scattering properties illuminated by wideband signals,echo signals of a point scatterer can be achieved.Since the responses of target are composed of many separate scattering centers when emitting wideband signals,the model of complex moving targets is created.For a special model,the simulations of scattering returns are presented.The results show that the simulations give a good characteristic of targets,which will assist in understanding radar target recognition.
