A Method to Reduce the Effect of 2-D Sampling Error on Pol-SAR Imagery

  • 摘要: 合成孔径雷达系统通常要对回波进行数字处理,方位向、距离向采样会给SAR点目标响应的峰值带来测量误差。该文针对此问题进行了深入分析,给出了峰值测量误差与点目标位置的关系。对时分工作方式多极化SAR系统的分析结果表明,在某些情况下,由方位向采样和非同时测量造成的极化数据间相对幅度和相位误差会很大。该文提出了使不同极化回波的匹配滤波函数相隔一定延时的匹配滤波方法,以使方位向采样对各极化数据具有相同的影响。仿真结果表明该方法有效地改善了极化数据间幅相一致性。该文研究的问题对SAR的精确定标有着重要意义。
