A modified matrix pencil method is proposed to simultaneously estimate the frequency pairs in multiple 2-D sinusoidal signals to bypass the computationally expensive pairing operation as seen in the literature. Simulation results show that the accuracy of the estimates for each frequency from our technique is better than or comparable to that of existing methods and the variance of the estimates are close to the Cramér Rao bound with lower computational complexity. © 2005 IEEE.
