A NEW METHOD FOR JOINT FREQUENCY-BEARING-ELEVATION ESTIMATION BASED ON FOUR-ORDER CUMULANT

摘要

A new method for joint frequency-bearing-elevation estimation based on four-order cumulant is presented. Several cumulant matrices are obtained by exploiting L-shape array geometries, to construct a high-order matrix to estimate three dimensional parameters. The proposed algorithm has the merits of no needing spectral peak searching and the good estimate precision, and it can be employed to white or color Gaussian noise environment. The effectiveness of our method is demonstrated through some simulation examples.
