摘要: The ability and how to use a microwave life-detection system search for the humans buried under earthquake rubble or laid behind various barriers has been investigated. Based on behavior of human multiple layers detection capability tools proposed. This operating at 1150 MHz can remotely detect movement heart trapped alive people. operation principle is based Doppler frequency shift electromagnetic wave reflected from periodic moving part living body such as heart. In this paper, parts patch antenna, directional coupler, band-pass microstrip filter, power amplifier, low noise are simulated using ADS2003A Microwave Office software. practical notes realization each have recommended. addition, through system, an overall systematic performance complete life investigated
