ABSTRACT

A prime problem of dealing with the consequences of earthquakes is the exact allocation of available rescue resources. Efforts of rescue teams should be applied to buildings, under which living people could be situated. This chapter presents an approach of technical means dedicated to the detection of living people under ruins, in rubble, and behind walls. The sub-surface video pulse radar and active radiometric systems are microwave devices used to search for people. The main aim of this radar is to search for a reflected signal from objects in a situation where the recorded reflected signal is from a human body trapped under ruins or behind walls. This physical model of the real prototype of ultra-wide band (UWB) radar was used in measurements carried out behind a wall of 70 cm thickness. The proposed UWB radar has to be able to detect exactly this modulation in the frequency range 0.1–10 Hz and suppress all other spurious signals.
