DoA Estimation with Sparse Arrays: Effects of Antenna Element Patterns and Nonidealities
Niko Lindvall, Mikko Heino, Robin Rajamäki +2
This paper studies the effects of directional antenna element complex gain patterns and nonidealities in direction of arrival (DoA) estimation. We compare sparse arrays and classic…

Sparse Active Rectangular Array with Few Closely Spaced Elements
Robin Rajamäki, Visa Koivunen
Sparse sensor arrays offer a cost effective alternative to uniform arrays. By utilizing the co-array, a sparse array can match the performance of a filled array, despite having sig…
