摘要

In this paper we consider the detection of a moving point target using two SAR antennas mounted on the same aircraft and spatially separated in the along track (cross range) direction. We consider two cases: conventionally quantized raw data and signum coded (SC or one bit coded) raw data. The performance of the presented along track interferometric system is evaluated by comparing the probability of false alarm and the probability of detection obtained in the two cases. Numerical results show that is possible to achieve comparable performances for both coding techniques.
