In this paper M-sequence ultra-wideband radar as a tool for the detection of people buried beneath rubble is described. Any strong enough motion of the victims modulates the signals detected by the radar. However, breathing is considered as the most beneficent type of motion, since it is present even when person is unconscious. Besides, the periodical nature of breathing makes it possible to distinguish it from noise and clutter components. After the enhancement of a useful target signature, radar signals contain the information which could possibly be used to increase the efficiency of rescue operations.
