N2 - In this paper, a coherent processing method based on valid poles and phase auto-focusing is proposed to compensate the incoherent phases between subbands in multiband radar signal fusion imaging. In order to eliminate the effect of noise on incoherent phase estimation, valid poles are firstly extracted based on the maximum cross correlation of subbands pole phase sequences, and then are reordered to estimate the linear incoherent phase. For the fixed incoherent phase estimation, phase auto-focusing which can effectively compensate the random initial phases is applied for subband echoes respectively. And the method is effective and noise insensitive as verified by simulation results.
