Modified signal modeling and imaging method of non-perpendicular crossing targets in forward scatter radar

In this paper, the shadow inverse synthetic aperture imaging method for non-perpendicular crossing targets is studied. Errors of the current signal model in both amplitude and phase are analyzed in this case and a more appropriate selection of the image plane is given. Modified signal model and imaging method are presented and evaluated by simulation results, which show that the given model fits the theoretical value well and the new imaging method provides more precise images than the old one.
