Abstract

Bistatic synthetic aperture radar (Bistatic SAR) have became the focus of increasing research activity these years, but the resolution of bistatic SAR is quite complex than that of monostatic SAR. In this paper, a general approach to estimate bistatic SAR ground range resolution based on spatial gradient is developed. This approach has more adaptability and can be agilely applied to different bistatic SAR configuration. The characteristic of gradient is analyzed and ground range resolution based on the spatial gradient is deduced. Detailed simulations test the validity of this approach and range resolution distribution in ground plane of airborne bistatic SAR is analyzed.
