Methods and Algorithms for Technical Vision in Radar Introscopy

Optimization of technical characteristics of radio vision systems is considered in the radars with ultra-wideband sounding signals. Highly noisy conditions, in which such systems operate, determine the requirements that should be met by the signals being studied. The presence of the multiplicative noise makes it difficult to design optimal algorithms of echo-signal processing. Consideration is being given to the problem of discriminating objects hidden under upper layers of the ground at depths comparable to the probing pulse duration. Based upon the cepstrum and textural analysis, a subsurface radar signal processing technique has been suggested. It is shown that, however the shape of the probing signal spectrum might be, the responses from point targets in the cepstrum images of subsurface ground layers make up the texture whose distinctive features enable objects to be detected and identified.

Radio Vision Systems Ensuring Movement Safety for Ground, Airborne and Sea Vehicles

This article presents the features of an all-weather radio vision system (RVS) ensuring the safety of movement of ground, airborne and sea vehicles and automation of vehicle traffic control under limited or non-existent visibility conditions. New and promising RVS applications in the aviation and rail transport sectors are presented. The potential use of RVS based on an interferometric radar with aperture synthesis, capable of estimating the position of ice fields and the height of icebergs is considered as well.
