Ground moving target detection method of parallel mode airborne bistatic SAR

  • 摘要: 提出了一种平飞模式机载双基地SAR地面慢速运动目标检测和参数估计方法.考虑到双基地SAR系统的特点,采用分数阶傅里叶变换(FrFT,Fractional Fourier Transform)技术对动目标进行聚焦,以提高动目标的信杂比.同时结合多通道杂波抑制干涉技术,进一步抑制地杂波并实现动目标参数的精确估计.从双基地SAR的空间几何模型和回波信号入手,推导了杂波对消时收发雷达载机所需满足的飞行条件和慢动目标参数估计的方法.最后通过计算机仿真,验证了该算法的有效性.
