摘要
在对雷达目标的动态特征提取和识别的研究中,需要能够逼真地反映目标的结构特性和运动特性的模拟信号。文中应用物理光学法和物理绕射理论,针对复杂动目标和多目标对目标面元和尖劈进行多普勒频率分级的方法实现了动目标的雷达散射截面计算;提出了微面元快速消隐算法和微动目标的模型剖分准则。应用该方法可以模拟转动、颤动以及非刚体运动目标的电磁散射特性。
In the studyh of the extraction and recognition of the radar target dynamic feature,a signal which can truthfully indicate the structure feature and dynamic feature of the target is needed.The calculation of the radar cross section of moving tar- gets is realized by method of gradation of the doppler of the facets and spikes,wiih the application of the physical optics and physi- cal theory of diffraction.A fast plate hidden algorithm and the profiling criterion of the model is proposed to calculate the Rada...
