摘要
从极化的观点出发讨论了复杂目标角闪烁的两种计算方法。基于电磁散射理论推导了考虑接收天线极化时PVM计算复杂目标角闪烁的一般公式;对采用PGM计算角闪烁提出了一种不需要进行"相位伸直"处理的算法;利用PGM和PVM计算和比较了不同接收极化下几种典型复杂目标的角闪烁线偏差,对基于组合偶极子模型获得的PGM和PVM的等效条件给出了一般性的数值证明。
Both the phase gradient method （PGM） and the poynting vector method （PVM） for computation of angular glint of complex targets are discussed from polarization consideration. The universal formulas of PVM with the consideration of polarization of receiving antennas are derived based on the electromagnetic theory. An algorithm that avoids inconvenient ＂phase unwinding＂ treatment is proposed for the computation of angular glint by PGM. The angular glint linear deviations of three complex targets are analyzed and compared for different polarizations by PGM and PVM. which numerically and generally verify the equivalent conditions between them based on two-point target consisting of two combined electric and magnetic dipoles with arbitrary orientation.
