摘要

针对非合作目标动态测量难以开展的问题,研究了基于FEKO的雷达目标动态极化散射特性实时仿真方法。首先给出了随时间变化的方位角和俯仰角的求解公式,然后介绍了利用FEKO实时仿真计算目标动态极化散射矩阵的方法及其步骤。仿真结果表明,机动目标的动态极化散射特性敏感于雷达视线角,雷达视线角变化越剧烈,插值法获得的极化数据越偏离实时仿真数据。验证了该实时仿真方法的有效性和准确性。

Abstract

The real time simulation method of dynamic polarization scattering characteristics of radar target based on FEKO was studied to solve the problem that the dynamic measurement of noncooperative targets was difficult to carry out. Firstly, the the formula of azimuth and elevation angle that varied with time variation were given. Secondly, the method and the procedure of the real time simulation and calculation of dynamic polarization scattering matrix of the targets using FEKO were introduced. The simulation results showed that the dynamic polarization scattering characteristics of maneuvering targets were more sensitive than radar aspect angle, and the more severe the change of radar aspect angle, the bigger the deviation of the polarization data obtained by interpolation from the real time simulation data was. The validity and accuracy of the real time simulation method were verified.

Key words： dynamic; real time; polarization scattering characteristics; FEKO; radar aspect angle
