通用的多模式SAR处理算法

Generalized processing for multi-mode synthetic aperture radar

标准条带成像处理算法不适用于新的合成孔径雷达成像模式.基于方位频率去斜原理,对多模式回波进行处理,使其具有一致的时频历程,从而实现通用的成像处理过程.对多模式SAR仿真回波数据的处理结果表明,采用这种算法能够实现各种模式的精确成像.

Based on frequency de-ramping principle,we present a method of making the relationships between azimuth time and Doppler frequency in different modes identical,which creates opportunity for devising generalized processing for all modes,and the proposed algorithms are supported by simulated multi-mode SAR data.
