无线电层析成像(RTI)是利用无线传感网络对目标成像的新兴技术，在区域目标监测与定位等方面有广泛的应用。该文研究基于无线网络链路损耗和层析成像机理的区域目标成像定位方法，在链路质量指标(LQI)的测量基础上构建了目标成像的网络结构，通过压缩感知中的匹配追踪重构(OMP)算法对目标图像进行重建，最后通过实验验证该方法的有效性。

Radio Tomography Imaging (RTI) is an emerging technology with Wireless Sensor Network (WSN) widely applied to regional target monitoring and positioning. This study explores target imaging based on tomographic imaging mechanism and the loss of multiple links in the wireless network. For this purpose, Link Quality Indicator (LQI) data and the network structure are examined to derive the method of target image reconstruction using the Orthogonal Matching Pursuit (OMP) algorithm for compressed sensing. In addition, the proposed method is evaluated experimentally.
