A Feedback based Detection Procedure with Low Communication Rate for Distributed MIMO Radar

This paper considers the detection problem and its realistic implementation for distributed multiple-input multiple-output (MIMO) radar system in severe environment with limited communication bandwidth such as land battlefield. In view of bandwidth improvement of modern wireless communication compared with the previous ones and the limitation of the bandwidth in battlefield environment, a distributed detection procedure with low communication rate is proposed. The local measurement information is censored and the remaining data are transmitted to fusion center for detection. Considering the bidirectional transmission of wireless communication, a new feedback mechanism is proposed. The fusion center and local decision results are fed back to the next detection, and the threshold is adjusted adaptively to obtain additional detection performance gain. Eventually, numerical simulations are carried out to verify the effectiveness and feasibility of the proposed procedure.
