Radio tomographic imaging(RTI)which uses received signal strength(RSS)measured by wireless transceivers is an emerging technology to imaging the attenuating objects.In this paper,we improve the performance of traditional RTI method by utilizing simple wireless nodes,employing inverse area elliptical model,adding nonnegative constraint to the regularization problem,and introducing direction into correlation matrix.Experiment results show that our RTI method of obstacle mapping can obtain higher image quality and lower mean-squared error(MSE)than traditional RTI method.
