建立合适的电磁散射模型是逼真地复现雷达目标的运动特性和回波特性的前提,而雷达动目标姿态角的计算是建立电磁散射模型的关键。文中提出了利用雷达目标的运动航迹求解雷达动目标姿态角的方法,并对其求解过程进行了推导,提出了任意姿态下进行动态雷达目标电磁散射特性仿真的一种思路。仿真计算结果验证了该方法的准确性和有效性,该方法可以在实际工程中推广应用。

Establishing appropriate electromagnetic scattering model is the promise of reappearing the moving characteristics of dynamic radar target realistically, in which the calculation of attitude angle is the key. This paper presents a method using moving trajectory of radar target to solve the attitude angle of moving target, derives its solving process, and gains the examples of calculating, which provides a way to simulate radar target electromagnetic scattering characteristics in arbitrary attitude angle. It is valid and accurate to analyze and resolve the problems in actual engineering application.
