Abstract:

For the problem of strong clutter when using ground penetrating radar (GPR) for landmine detection, a low rank and sparse decomposition (LRSD) based method is proposed. The proposed method introduces weighted nuclear norm (WNN) into robust principle component analysis (RPCA) and combines randomized singular value decomposition (RSVD) with the alternating direction method of multipliers (ADMM) to solve the optimization function, which suppresses the clutter by treating the target image as sparse component and the clutter image as low rank component and enhance the accuracy and efficiency of the proposed algorithm. The experimental results show that the proposed method can significantly improve the signal-to-clutter ratio (SCR) of the imaging results and the computation efficiency is over five times than that of the RPCA, which demonstrates the efficiency in clutter mitigation.

Key words: clutter suppression, low rank and sparse decomposition (LRSD), alternating direction method of multipliers (ADMM), ground penetrating radar (GPR)
