SINOPSIS

In the article are motivated the main requirements to the radar features from standpoint of conditions of the wave propagation on short, lumpy or composition path, so there are considered problems of the choice of the radar station structures, intended for finding the alive people under blockages of buildings. Complex conditions in which it is necessary to work to systems of a similar sort causes the requirements to radar signals. Presence of multiple interference complicates creation of optimum algorithms of processing of echo-signals. Application of signals with the big base and a complex kind of modulation demands creation of the hardware means providing precision accuracy of formation and processing of a signal. Merits and demerits of various variants of construction of block diagrams of radars for detection of people under blockages are discussed. Results of computer simulation are given.
