Improved cross-correlated back-projection algorithm for through-wall-radar imaging

This paper mainly deal with the degradation of the cross-correlated back-projection (CBP) imaging quality in the case of through-wall low signal-to-noise ratio (SNR), and an improved CBP algorithm is proposed to implement high-quality through-wall-radar imaging. Through accumulating all the sampling points rather than one sampling point of the cross-correlated target echoes into target location, the formed image is provided with the higher SNR. Besides, the advantages of artifact suppression and cross-resolution enhancement in CBP are inherited by the improved CBP. This approach is validated by the simulation results.
