Doppler Spectrum of Backscattered Field From Time-Varying Sea With a Low-Flying Small Target Above It

摘要：

　　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 lowflying small target above time-varying sea surface is investigated in this paper.
