摘　　要：无线电层析成像（RTI）是通过分析因环境改变引起无线链路接收信号强度（RSS）的变化情况来推测场景信息的过程。文章运用一种新的链路分析方法，通过分别分析场景目标对链路的两种影响，即因阻挡而阴影衰减的影响和因反射而使链路多径分量增加的功率增强影响，得到不同的场景信息，最后综合两种信息得到场景信息，大大减少无线信号噪声干扰，通过实验证实该方法能减少噪声对RTI的干扰，实验结果有较好的收敛度。Radio tomographic imaging （RTI） is a process of infer scene information by analyzing the changes of wireless link＇ s received signal strength （RSS） due to environmental change. Here propose a new approach for link RSS analysis which clas- sification the RSS difference into two parts, the links which RSS attenuation due to shadow by target and the links which RSS enhances for the reseason of have additional multipath components made by target＇ s reflected, get the different scene informa- tion and then comprehensive analysis scene information. Through comprehensive analysis, greatly reducing the effect of wire- less signal noise, Experiment results are presented.
