摘要 由于在观测带内采用了多波束扫描的工作模式,使得ScanSAR产生了固有的周期性的scalloping效应,影响了ScanSAR的辐射特性。该文基于ScanSAR工作模式的特点,研究了scalloping产生的机理和性质,定量地分析了scalloping引起的辐射误差以及多普勒中心误差与scalloping的关系,并研究了对scalloping进行校正后的剩余误差问题。 Because of the multiple-beam scanning strategy in swath, the intrinsic periodic scalloping exists in ScanSAR, which affects the radiometric property of ScanSAR. Based on the character of ScanSAR, the mechanism and property are studied, radiometric error caused by scalloping and relation between Doppler centroid error and scalloping are quantificationally analyzed. The residual error after correction is also studied.
