This paper shows the ability to use a continuous wave (CW) radar as an instrument to search for trapped alive persons in demolished buildings and ruins. The utilized operation principle is the detection of the Doppler frequency shift of the E/M wave when it is reflected by a slightly moving part of a living human body. The presented system has gone through several prototype development phases. Many parameters and alternative implementations have been tested in both real and simulated sites. A system analysis is carried out and presented followed by a presentation of the signal processing techniques. The inherent difficulties for the realization and practical exploitation of such a system are discussed. Results from tests of the system are also presented.
