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