%X This paper studies on the speckle reduction in multi-look polarimetric SAR image. A novel method, named the multi-look polarimetric whitening filtering (MPWF) method, is presented, and is further extended to construct a fully polarimetric filter with multi-channel output. The paper also quantifies the amount of speckle reduction achievable by using the MPWF, and compares this method with the span, weighting and power equalization (PE) methods in theory. Experimental results with the NASA/JPL L-band 4-look polarimetric SAR data demonstrate the effectiveness and superiority of the MPWF, and show that the MPWF is of great advantage for enhancing SAR image classification.
