摘要
合成孔径雷达（ＳＡＲ）的成像处理需要大规模的运算量和转置存贮量，因此对处理硬件要求高，且实时率难于提高。文中提出了一种基于重新安排处理顺序，相干叠加和滤波处理的高效处理算法，在分辨率相同时，该算法在转置存贮量增加２５％，图像质量略有下降的情况下，可将运算量减少５０％～６０％。
Data processing of synthetic aperture radar needs a large amount of calculation and cornerturning memorization. The requirement for processing hardware and processing speed is proved to be very difficult to raise.This peper Puts forward a high-efficiency processing algorithm based on processing sequence rearrangement, coherent addition and FIR filtering, It decreases 50% ￣ 60% of the calculation amount of regular algorithms, with 25% increase of corner-turning memorization and a little decrease of the image quality.
