摘要：

This paper discuss the use of a bistatic antenna configuration for ground moving target indication in an ultra-wideband and widebeam synthetic aperture radar system. To suppress the strong clutter signal the radar channels have a strict requirement on equality. In a bistatic system they are not equal, and in this paper we investigate how to compensate for the bistatic configuration. Bistatic effects on clutter scattering can not be compensated, and we therefore attempt to estimate the bistatic scattering influence of the ground moving target indication. The bistatic to monostatic synthetic aperture inversion in a wide antenna beam is derived both in the time and frequency domain. The mismatch between the radar channels will cause clutter leakage. The pulse compressed impulse response leakage are determined both for the time and frequency domains.
