The analysis of the current state and tendencies in radar development shows that novel methods of target viewing are based on a detailed study of echo signals and their informative characteristics. These methods are aimed at obtaining complete data on a target, with emphasis on revealing new steady parameters for their recognition. One way of raising the efficiency of radar technology is to improve available methods of radio vision, or imaging. Radio vision systems provide a high resolution, considerably extending the scope of target detection and recognition. This field of radar science and technology is very promising, because it paves the way from the classical detection of a point target to the imaging of a whole object.
