Superresolution DoA Estimation With Circular Arrays Using Signal Segregation Algorithm in Conjunction With a Nulls-Synthesis Method

A method for superresolution direction-of-arrival (DoA) estimation of correlated signals using a circular array is presented. This is accomplished in two steps: 1) the directions of arrival and amplitudes of signals with angular spacing larger than the array beamwidth are detected using the array si...
