相位梯度自聚焦算法在机载合成孔径雷达运动补偿中的应用
Application of an improved PGA algorithm in SAR motion compensation
【摘要】 研究了机载合成孔径雷达运动补偿中可以补偿任意阶相位误差的相位梯度自聚焦(PGA)算法,提出一种PGA快速算法。与雷达成像算法结合后,图像测量精度得到提高。
【Abstract】 A PGA algorithm,which can compensate any-order phase error in airborne SAR motion compensation,is discussed in this article.A fast PGA algorithm is also proposed.Combined with radar imaging algorithm,the operation speed is faster,and the image measuring precision becomes more accurate.
