Direction Finding with Sparse Arrays Based on Variable Window Size Spatial Smoothing
Wesley S. Leite, Rodrigo C. de Lamare, Yuriy Zakharov +2
In this work, we introduce a variable window size (VWS) spatial smoothing framework that enhances coarray-based direction of arrival (DOA) estimation for sparse linear arrays. By c…
