Minimum Array Elements and Snapshots for Performance Analysis Based on Direction Of Arrival (DOA) Estimation Methods

Abstract

The minimum array elements and snapshots for performance analysis of several Direction of Arrival (DOA) estimation methods are presented in this paper. The DOA algorithm’s effectiveness is evaluated by its ability to resolve several spaced signals. Previous studies have been concerned with determining the impacts of the design parameter on the results of the DOA techniques. These studies concentrate on the impact of no more than two sources that impinge on an antenna array. In the true globe, there are several multipath and Angles of Arrivals (AOA) that interfere with the initial signal. The receiver site must, therefore, be able to calculate the AOA and decipher the presented transmitters with their angular locations. This research takes into account the impacts of interference and multipath. The emphasis was placed upon the study of the minimum number of snapshots and array elements needed to solve multiple interfering signals for a range of different DOA procedures. The result shows that over other algorithms the MUSIC algorithm has the best result.
