Abstract

A new array design for azimuth direction of arrival (DOA) estimation is proposed in this work, known as semicircular array. The structure of proposed array occupies half of x-y plane with the capability of two-dimensional (2D) DOA estimation. Computer simulation is performed to evaluate the performance of proposed array in azimuth DOA estimation using Capon algorithm. DOA estimation results of proposed array are then compared with circular array based on resolution and error of estimation. Simulation results show that the proposed array achieves 50% better resolution of estimation than circular array. Further examinations also reveal that the proposed array acquires not less than 75% better estimation error than circular array. This work concludes that the proposed array offers an alternative design in array geometry with better quality in DOA estimation.
