摘要
针对机载合成孔径雷达ＳＡＲ斜侧视成像的二维处理特性，采用一种全聚焦的处理方法，它能方便地处理斜侧视ＳＡＲ参考函数的空间变化的特性，并提高计算效率。
This paper investigates the two-dimensional features of the strip imaging of the suint modeside-looking airborne SAR and the space-variance of the SAN system transfer fundion which is due to thefocus depth variation and the squint angle. It introduces aprocedure for efficient space- variancecompensation which is based on the use of a modified kernel FFT (MKFFT) algorithm. It is a fully focusedprocedure to squint mode side-looking SAR imaging. And it has high computational efficienty. It is notedthat the procedure can be easily accommodated to include squint aberration correction. The computersimulation results confirm the procedure to squint mode SAR imaging.
