Abstract In this work, a combined direction-of-arrival (DoA) estimation method for a four element square array is presented. A four element array is a very small planar array and estimation performance with ordinary DoA estimation techniques is considerably low. Main goal in this work is to improve the estimation performance of such an array by estimating the DoA with different geometrical configurations of the array elements and combine the results to evaluate the resulting DoA estimation. The geometrical structures employed are based on the circular, L shaped and linear configurations of the array elements. Performances of the geometries are evaluated and a combining filter based on the weighted results of the geometries is generated. The weighted results evaluated at the output of the filter are superior when compared with individual results of each of the geometries.

This paper proposes a precise and fast direction of arrival estimation method using Global Navigation Satellite System (GNSS) carrier phase measurements. Single-epoch, single-satellite integer cycle ambiguities are reliably resolved by making use of constraints and taking advantages of antenna arrays. The algorithm shows good robustness in cases where signal interruption or corruption occurs on some antenna elements as long as four antenna elements in a non-planar array have uncorrupted observables. The algorithm is demonstrated by field tests where antenna elements are connected to multiple receivers with an external common clock. The results indicate a high success rate of single-epoch ambiguity resolution and high direction of arrival accuracy.
