Abstract
Existing ultra‐wideband (UWB) radars for buried survivor detection operated at high center frequencies and had limited penetration capability.A new UWB radar operating at a center frequency of 500 MHz is developed in this article. The experimental results show that it can detect the respiration of human subjects lying under a simulated earthquake rubble of about 2 m in thickness. Thus this new radar is practicable and promising for detecting buried survivors after an earthquake. © 2010 Wiley Periodicals, Inc.
