摘要 将多极化星载SAR系统与距离向数字波束形成技术相结合,提出了多极化星载SAR"空分+码分"工作方式.在"空分+码分"工作方式下,发射信号时,在一个脉冲重复周期内首先水平极化天线发射子脉冲,为水平极化的正线性调频斜率线性调频信号,延时一定时间后,垂直极化天线发射子脉冲,为垂直极化的负线性调频斜率线性调频信号,实现码分;接收信号时,方位向和距离向多孔径同时接收,利用距离向数字波束形成分离出前后脉冲所对应的各极化回波分量,实现空分.该系统脉冲重复频率等于单极化SAR系统脉冲重复频率,同时距离向使用数字波束形成技术有效降低了距离模糊.文中分析了主要系统参数,包括脉冲重复频率、孔径间发射脉冲延时、模糊度,并与传统单极化SAR进行了比较.仿真结果表明多极化星载SAR采用"空分+码分"工作方式是可行的,并具有较好的特性.
