            Abstract : 
We consider non-homogeneous 2-D signals which can be represented by a constant modulus polynomial-phase model. We develop a computationally efficient estimation algorithm for the parameters of this model. The algorithm is based on a phase differencing operator which is introduced in this paper. The basic properties of the operator are derived and used to develop the estimation algorithm
