摘要
超宽带废墟搜救雷达是一种新型的搜救设备,在地震等灾害后的救援工作中能够发挥重要的作用,但现有搜救雷达一次探测仅仅只能够识别单个生命体目标,缺乏多生命体目标探测识别的能力,因此提出一种多生命体目标识别的方法。详细叙述了超宽带废墟搜救雷达多生命体目标识别方法的整个信号处理过程,从原始雷达数据的获取,到信号预处理中道内数据压缩、时域积分及无量纲化,再到如何进行多生命体目标识别都有详细的介绍,并在每步处理中给出了实测数据的处理结果,从结果中可以看出所给方法的有效性与可行性。
Ultra wide band（UWB）ruin？rescue radar is a new search and rescue equipment,which can play an important role in rescue operation after earthquake and other disasters. Since the existing search and rescue radar can recognize single life target once,and lacks the ability of detecting and recognizing multi？lift target,a multi？life target recognition method is pro？posed. The whole signal processing procedure of the proposed life recognition method based on UWB ruin？rescue radar is de？scribed in detail. The process of radar data acquisition,data compression,time？domain integral and undimensionalization in sig？nal preprocessing,and how to recognize multi？life target is introduced at length. The processing results were provided in each？step processing,which shows that the proposed method is validity and feasibility.
