说明：  matlab实现加汉明窗，矩形窗，并对它们进行傅里叶变换，并实现频谱的分析。(matlab realize Jia Hanming window, rectangular window, and they are subjected to Fourier transform, and to achieve the analysis of the frequency spectrum.)

在FFT后信号的频率往往与谱线不相重合，而在两条谱线之间。为了要求得信号的频率、幅值和初始相角，必须要使用修正法来完成。这里给出一种修正法。(After the signal in the FFT frequency spectrum often do not coincide, and in between the two lines. Request for a signal frequency, amplitude and initial phase angle, we must use to complete the Amendment Act. Here are a Amendment Act.)

利用Matlab软件进行可视化操作，从而达到压缩图像的目的。(To squeeze images by the agency of a visible software called Matlab.)

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)
