A Novel 2D Off-Grid DOA Estimation Method Based on Compressive Sensing and Least Square Optimization
For two-dimensional (2D) direction of arrival (DOA) estimation in a uniform rectangular array (URA), the conventional method converts the 2D problem into a one-dimensional (1D) problem; however, the computational complexity is high, and the accuracy is limited by the grid interval. To address this i...
