چکیده:

The superiority of multiple-input multiple-output (MIMO) radars over conventional radars has been recently shown in many aspects. The target tracking in MIMO radars isone of these aspects that has not been considered thoroughly yet. These radars consist of many transmitters and receivers locatedfar from each other. In this scenario, the MIMO radar is able to observe different aspects of the target. One of the advantages of these radars is exploitation of Doppler frequencies from differenttransmitter-target-receiver paths. The extracted Doppler frequencies can be used for estimation of target velocity vector sothat, the radar can be able to track the targets by use of its velocity vector with reasonable accuracy. In this paper, the pulseDoppler processing in MIMO radars is considered. The measurement of the velocity vector of the target and its counterpart errors is taken in to account. The extended Kalmantarget tracking by using its velocity vector is considered too. 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 radars usingvelocity vector have superior performance over conventional radars in fast maneuvering target tracking.
