Abstract :
In a recent paper [1] a model for radar images was derived and a method for mean-square error (MSE) filtering of noisy radar images was presented. The purpose of this correspondence is to point out that the filter in [1] is not optimum in the MSE sense and to show that the ultimate filter scheme is based on a very restricted model for radar images.
