N2 - In the ground-based FSR, the strong ground reflected signal seriously cancel the useful signal, as a result the estimation methods of the target images in current SISAR imaging technology are no longer applicable. The height difference of the target can't be estimated from the amplitude of complex profile function (CPF). In this paper, firstly, the multipath interference on the forward scatter (FS) signal model and imaging results of the moving target are analyzed by the two ray path model. Then, the estimation methods of the target profile image under multipath interference condition are presented. As a result, the accurate target images that cannot be achieved by using the current imaging algorithm can be extracted using the modified imaging algorithm. Finally, the effectiveness of the estimation methods is validated by the simulations.
