Angle and Doppler estimation using alternating least squares method in bistatic MIMO radar

This paper proposes a novel alternating least squares (ALS) method for joint angle and Doppler frequency estimation in bistatic multiple-input multiple-output (MIMO) radar. Via iteratively estimating the transmitting, receiving and Doppler steering vectors of multiple targets from the received signals, ALS can simultaneously obtain the two-dimensional (2-D) angles and Doppler frequency of the target. Simulation results illustrate the rapid convergence rate and high estimation accuracy of this method.
