Abstract: Life detection technology based on a single type of information sources can’t completely meet the needs of the earthquake relief， because they can’t make up for their own defects. This paper introduces the existing life detection techniques including acoustic wave life detection， optical life detection and radar life detection. The advantages and existing problems of the three life detection techniques are also analyzed. The advantages and present situation of multi-sensor detection synergy technique are given. The life detection synergy platform is designed with infrared and acoustic wave in this paper. And the platform structure model， multi-sensor selection strategy and performance index are introduced too. Finally， the development direction of life detection technique based on multi-sensor synergy is forecasted. This platform can synchronously collect， analyze and process infrared image and acoustic wave， has the functions of audio life detection and video detection function， makes up for the deficiency of the single sensor life detector. It can get more comprehensive and more accurate information about the scene of rescue and living organisms， and it is more suitable for complex quake rescue environment.
