Abstract

A disadvantage of monostatic SAR is that it cannot image the forward-looking area. In this paper, the possibility of forward-looking imaging with bistatic configuration is verified using DVB-T signals as transmitting signals. The Back Projection (BP) method is used to perform the imaging in each configuration and the point spread functions (PSFs) are presented. The forward-looking imaging ability is analyzed in terms of the resolution for each configuration. From the simulation, we realized forward-looking imaging with bistatic Radar in configuration 3, that is, the squint angle has been reduced to zero. The result show that bistatic forward-looking imaging is feasible and the resolution can achieve the requirement.
