| 摘 要： | 地震后的救助现场情况错综复杂,通过对受困人员发出的各种求救信号的分析,确定适合现场搜救的有效信号,而定位方法的研究是研制和开发声波/振动生命搜索与定位系统的基础.考虑现场救助的困难和时间要求,提出了能量追踪的快速搜索方法.参考天然地震震源定位Giger法,提出了一种能够适用于地震救助现场,基于振动直达波到达时差的定位方法--4点时差定位的搜索理论方法,为声波/振动生命搜索与定位系统的开发提供了理论基础.

| Abstract: | On the earthquake rescue site,there are many kinds of signals come from the victims.The research on the victim location system based on the acoustic and seismic wave detection plays an important part in the earthquake emergent life salvation.After a careful analysis,by choosing the most effective signals and by referring to the classical location method attributed to Geiger,the authors established the four-point time difference of arrival(TDOA) search and position method.This method can locate the position of the survivors in an earthquake and provides the theory foundation for the development and application of the acoustic/seismic life detector. |
