The problem of prompt detection of people affected during various kinds of catastrophes in ruined buildings, accidents in mines, quarries, accidents caused by snow avalanches, mudflows and landslides has discussed. The problems of creating portable remote sensing devices for people behind optically opaque barriers has detalied illuminated in theoretical and practical aspects. Main attantion paied to class of short-range doppler radar with continuous pseudo-noise phase-code modulation of the probing signal. Presented and discussed the different methods how to isolate the information signal against the background of interference caused by reflections of the sounding signal from local objects, obstacles on the propagation path, and subsequent decision making about the presence or absence of the target in the interest area. The book summarizes the author's experience in developing the theory and technique of digital processing of information signals of radar systems for the detection of living people hidden by optically opaque obstacles. A mathematical apparatus and results of simulation of signal processing algorithms are described. The results of experiments are presented.
