摘要

本文采用准平稳算法,即通过重复执行频域方法逼近时域问题,研究时变海面上运动目标的后向散射回波的多普勒频谱。为了快速准确地求解时变海面上低空小目标的复合散射问题,本文采用Kirchhoff近似(KA)和矩量法(MoM)的混合算法对时变海面的多普勒频谱特征进行了分析。研究了目标飞行速度对时变海面低空飞行小目标多普勒频谱特征的影响。

Doppler Spectrum of Backscattered Field from Time-Varying Sea with a Low-Flying Small Target Above It
In this paper, the Doppler spectrum of backscattered echoes from moving target above time-varying sea surfaces is investigated by utilizing the quasi-stationary algorithm, i.e., approximating the time-domain problem by repeatedly implementing the frequency-domain method. In order to fast and accurately solve the composite scattering problem of time-varying sea surfaces with a Low-flying small target above it, a hybrid algorithm of Kirchhoff approximation (KA) and method method-of-moments (MoM) is utilized in this paper for analyzing the Doppler spectrum signatures. The effect of the speed of flying target on Doppler spectrum signatures of a low-flying small target above time-varying sea surface is investigated in this paper.
