Abstract
High-resolution diffraction tomographic (DT) ground-penetrating radar (GPR) image formation requires the use of wideband signal and large antenna array aperture, which leads to the generation of large amounts of imaging data. A compressive sensing multibistatic GPR DT imaging algorithm is presented in this letter. The proposed imaging algorithm can provide the advantage in terms of reducing the measured data in the frequency domain while maintaining the image quality of the reconstructed scenario. The imaging results reconstructed via the processing of synthetic data have verified the validity and effectiveness of the proposed imaging method.
