说明：  这是SAR成像点目标仿真中的wK算法，程序严格按照Ian G. Cumming的《合成孔径雷达成像算法与算法》中wK算法来编写，对于学习wK算法的同学来说是入门级的仿真程序
(This is the the SAR imaging point target simulation the wK algorithm, the program written in strict accordance with the Ian G. Cumming synthetic aperture radar imaging algorithm and algorithm wK algorithm for students learning wK algorithm is entry-level simulation program)
