| titleOfInvention | Forest or urban area high-resolution interference phase filtering method |
| abstract | The invention relates to the technology of interference synthetic aperture radar imaging and discloses a forest or urban area high-resolution interference phase filtering method. The method is applied to forest or urban area high-resolution interference phase image filtering and overcomes defects of widely-distributed massive random noise or the low-coherent area, an independent identically-distributed sample is selected from a whole frame of interference phase image, the operation amount is reduced, searching of the independent identically-distributed sample is limited in a window which has the fixed size and takes a pixel to be filtered as the center, and the window is named a filtering window. The selection process of the independent identically-distributed sample is achieved by recognizing and removing outliers in the filtering window, and the outliers can represent pixels which cannot meet independent identically distribution with the pixel to be filtered in the filtering window. On the premise of effectively interfering stripe details, the method obviously reduces the number of residual points in the interference phase image, effectively improves the noise restraining effect and improves the filtering performance of the forest or urban area high-resolution interference phase image. |
