摘要(Abstract)：

针对面向震后应急救援的压埋人员位置估计中传统探测设备成本高、受压埋环境影响大等不足,利用RSSI测距技术,以压埋人员Wi-Fi设备发出的Wi-Fi信号在压埋物下经最小信号损耗穿出对应的信号穿出点为压埋人员的平面位置,该文提出了一种无需已知压埋环境的压埋Wi-Fi设备的快速定位算法,较好地克服了信号在压埋物下大幅、不可知损耗与在外部复杂环境中多路径传播的问题。该算法在建立震后压埋Wi-Fi设备的信号传输模型的基础上,使用高斯-频谱分析处理RSSI数据,得到含有压埋信号损耗的最优路径距离值,通过附有系统参数的加权最小二乘平差方法,结合粒子群寻优算法,得到压埋人员的平面位置。实验结果表明,使用改进的RSSI快速定位算法进行压埋Wi-Fi设备的定位,有效地改善了定位精度,其数值在1 m左右且时效在几秒内,以此达到解决压埋人员应急救援的快速定位问题的目的。
