Foreign object debris(FOD)detection in airport runway is very important to airplanes′safety,and the airport runway radar image noise suppressing plays a vital role in foreign object detection.Therefore,an airport runway radar image de-noising method based shift invariant hybrid transform is proposed in the rangetime dimension.Firstly,the radar image noise in the range dimension is removed by the Wiener filter in discrete Fourier transform(DFT)domain.Secondly,the radar image noise in the time dimension is re...
