Investigation of Direction Finding Algorithms for a Circular Ring Array of Various Aperture Sizes

This work investigates the direction-finding performance of a ring of various radius sizes and compares the performance for both a periodic and a random assortment of sensors. The topologies are filled with isotropic radiators, and the overall distribution is generated as a random filling of the topology or a periodic filling along the perimeter. Last, the direction-finding capabilities of circular arrays of different size radii are simulated in this work using MATLAB with comparisons of the periodic and randomly distributed sensor arrays using three different direction finding algorithms.
