Resolution analysis of bistatic SAR

摘要

In this paper, we analyze the resolution of bistatic synthetic aperture radar (BISAR) imaging for stationary objects. In particular, we analyze the resolution of images reconstructed by the method of a filtered backprojection inversion, an inversion method which is derived from a scalar wave equation model. In this context we are able to account for the effects of antenna beam patterns and arbitrary flight trajectories. The analysis is done by examining the data collection manifold for different experiment geometries and system parameters.
