Controllability And Observability

A study of a two-dimensional state-space balance (2D SSB) method for estimating direction of arrival (DOA) for uniform rectangular array (URA) is presented in this letter. The comprehensive utilization of controllability and observability matrices and automatic pairing technique are considered in this method by using the single snapshot. Therefore, the DOAs of elevation angle and azimuth angle can pair automatically and acquire better estimation performance compared with 2D matrix pencil method or unitary matrix pencil method. In addition, the proposed method can handle correlated signals directly without preprocessing. Simulation is conducted to verify the effectiveness of the proposed method.

Variant Method

The problem of estimating two-dimensional frequencies of multiple sinusoids embedded in noise is addressed. A variant of the recently reported matrix pencil method is proposed. Numerical results that provide insights into the perturbation deviations of the estimated two-dimensional frequencies are given for both methods. The variant method is shown to be computationally much more efficient than the original method while their accuracies are comparable.
