Abstract

A principle of shadow imaging for bistatic radar based on forward scattering is introduced. Joint time frequency characteristics of target signal and ground clutter are analyzed

then a method of eliminating ground clutter in bistatic radar echo by wavelet analysis is presented.A robust motion compensation method——to estimate radial motion parameters of target by time-frequency analysis is presented.Finally

the effectiveness of these methods is shown by the results of computer simulation.
