A new hybrid lattice structure to identify the parameters of an unknown 2D ARMA (M, N) system, where M and N can take arbitrary values different from each other, has been presented. The proposed hybrid analysis model incorporates both two-channel and single channel lattice stages in an interleaved manner. The two-channel lattice part is based on the formerly proposed 2D ARMA lattice modeling approach where only the case Al-N was covered. A new formulation to calculate the ARMA parameters has been derived taking the estimated parameter b(0) into consideration.
