Abstract:
In this paper, we address the problem of Direction of Departure (DOD) and Direction of Arrival (DOA) estimation for Multiple Input Multiple Output (MIMO) radar. The presented work studies the effect of Radar Cross Section (RCS), Signal to Noise Ratio (SNR) and speed of targets on the performance of the MIMO radar with widely and closely separated antennas. Since the information on the targets is obtained from the echoes of the transmitted signals, it is straightforward that RCS and speed of targets play an important role in system accuracy. Analysis can be used to find the direction of multiple types of targets such as Capon, Multiple Signal Classification (MUSIC) and parallel factor (PARAFAC). To differentiate the meaning of targets, varying targets of different types, such as bicycle, bird, man, ship and jet have been considered. After defining suitable values for each type of target in 2D space, the performance of each type is discussed by using the MATLAB program. Finally, we present an experimental platform of MIMO radar with Bistatic antennas which has been developed in order to evaluate the performance of the above techniques under more realistic conditions.
