通过多层次态势感知实现对战场的高效率侦察是未来战争的必然趋势,合成孔径雷达是实现上述目的的重要技术手段之一。文中提出凝视可重构合成孔径雷达(SAR)系统,该系统在发射端采用脉间线性调频信号,在接收端通过数字信号处理的方法,在系统参数约束下,对回波信号进行重构,以满足系统需要实现不同幅宽和分辨率的成像需求,达到单 次观测获取多层次信息的目的。并通过数值仿真验证了该系统在技术上的原理可行性。

This is the tendency that achieving the battlefield surveillance efficiently by multi-level situation perception in further war. The synthetic aperture radar (SAR) is the important method to achieving the purpose above mentioned. This paper introduces the staring reconfigure SAR system. In this system, the inter-pulse linear chirp signal is employed in transmitter, and the digital signal process algorithm is employed to reconfigure the echo under the limited of the system, to meet the need of imaging with the different swatch and resolution. Then the multi-level information of battlefield can be obtained by single observation. The number simulation is proved the available of the system.
