Both direction and time of arrival estimation by using beamforming and MUSIC algorithm for stepped FM array radar

In this research, we propose a method to estimate both direction of arrival (DOA) and time of arrival (TOA) using stepped FM radar system. The method uses beamformer and MUSIC algorithm with respect to time and space. The multiple target f s directions and distances are estimated accurately, and they are combined to represent the parameter of each target. Some simulations are performed and they show the validity of our method.
