Post-processing of multi-look and sequentially formed images in radar and ultrasonic coherent systems

The peculiarities of post-processing of multi-look synthetic aperture radar (SAR) images and ultrasound image sequence with the aim of their enhancement are considered. It is shown that it is expedient to apply both several image accumulations and their further filtering. For test and real data the comparison analysis of several methods of image accumulation and filtering is performed and practical recommendations concerning their application are given.
