Target Tracking in MIMO Radar Systems Using Velocity Vector

The superiority of multiple-input multiple-output (MIMO) radars over conventional radars has been recently shown inmany aspects. These radars consist of many transmitters and receivers located far from each other. In this scenario, theMIMO radar is able to observe the targets from different directions. One of the advantages of these radars is exploitationof Doppler frequencies from different transmitter-target-receiver paths. The extracted Doppler frequencies can be used forestimation of target velocity vector so that, the radar can be able to track the targets by use of its velocity vector withreasonable accuracy. In this paper, two different processing systems are considered for MIMO radars. First one is thepulse Doppler system, and the second one is continuous wave (CW) system without range processing. The measurementof the velocity vector of the target and its counterpart errors are taken into account. Also, the extended Kalman targettracking by using its velocity vector is considered. Besides, its performance is compared with those of MIMO targettracking without using the velocity vector and conventional radars. The simulation results show that the MIMO radarsusing velocity vector have superior performance over other above-mentioned radars in fast maneuvering target tracking.Since the range processing is ignored in CW MIMO radar systems, the complexity of this system is much lower than thatof Pulse Doppler MIMO radar system, but has lower performance in tracking fast maneuvering target
