Simulation study demonstrates a closed-form maximum likelihood estimator using three subapertures for resolving closely spaced radar targets, suggesting simplified high-accuracy angle tracking.
The maximum likelihood estimates of the elevation angles of two closely spaced targets within the beamwidth is considered. For an array divided into three subapertures, a simple, closed form solution is found whose accuracy compares favorably to the maximum likelihood estimate which uses all the individual elements. Simulation results are presented for the case of a radar target located over a smooth reflecting surface.
