Abstract
We consider nonhomogeneous 2-D signals that can he represented by a co nstant modulus polynomial-phase model. A novel 2-D phase differencing operator is introduced and used to develop a computationally efficient estimation algorithm for the parameters of this model. The operation of the algorithm is illustrated using an example.
