Abstract :
A computationally efficient direction-of-arrival (DOA) estimation algorithm is proposed for the multiple-input multiple-output (MIMO) radar with uniform linear array (ULA). In the proposed algorithm, the ULA structure is exploited to greatly reduce the array vector dimension, which results in a significant decrease in computational complexity. The effectiveness of the algorithm is verified by simulations.
