Restoration of signal coherence in radio image processing

An optimal statistical approach is applied to the task of radio image building. The physical essence of the task is as follows: wideband pulse radio radiation is being reflected by the moving object. As a result, two-dimensional aperture is being synthesized: along the range - by means of super resolution, along the velocity - by means of object moving. The radio signal is received by a single radio receiver. The object image is reconstructed from this signal by the maximum likelihood method. The method uses a coherent treatment of signals. In practice the coherence can be destroyed. An algorithm for restoration of the coherence is proposed. The algorithm is based on the properties of undistorted images in the far Fraunhofer zone of surveillance. The quality of the images is tested by digital modeling. The results are shown in pictures
