Abstract

In this paper, the compressive sensing (CS) method is used in the through the wall radar imaging (TWRI) to reduce the measurement points and data acquisition time, consequently. In fact, the large required amount of measurement points is considered as one of the main challenges in TWRI which can be mitigated by this proposed method. The diffraction tomography (DT) method is the most effeicient conventional method used in TWRI process. By exploiting the advantages of the CS and non uniform fast Fourier transform (NUFFT), the effectiveness and speediness of the DT method is significantly increased. Simulation and experiment results have verified the validity of the proposed imaging method.
