Abstract :
In this paper, a new system called non-uniform linear antenna array SAR (NULA-SAR for short) is proposed. Using multiple complex images formed by multiple antennas with special configuration, NULA-SAR can not only suppress the stationary clutter, but also locate and image both slowly and fast moving targets accurately. Numerical experiments are presented to demonstrate the effectiveness of NULA-SAR
