说明：  雷达信号去斜处理方法：去斜处理(宽带的匹配滤波)Stretch方法是针对线性调频信号而提出的, 其方法是将输入信号与参考信号 (经适当延迟的本振信号, 延迟量通常由窄带信号测距结果估计出) 混频(Radar signal de-obliquation processing method: The Stretch method of deskew processing (wideband matched filter) is proposed for linear frequency modulation signal. Its method is to mix the input signal with the reference signal (local oscillator signal with appropriate delay, the delay is usually estimated by narrowband signal ranging result))

denoising filters such as Average, Median, Gaussian, Wiener, Min-order-statistic, Maxorder-statistic and Median-order-statistic are used. Based on the images obtained by the mentioned filters, it is become obvious clear that for the given noisy image the Min filter acted much better than the other filters. Order-statistic Median and Gaussian filters are the ones that have a second and third good result respectively. That is way can conclude that the existing noise in the given image was Salt noise.
