Abstract:

In order to make full use of the flexibility of antenna selection for higher location accuracy and lower system cost of multiple targets tracking in distributed multiple input multiple output radar system, an antenna selection algorithm based on multiple targets location estimation is proposed. Firstly, an optimization criterion improving estimation accuracy of the targets location is derived, and a compromise model on estimation performance and system cost is established under the constraint of subset size and the highest accuracy error. Then, the corresponding antenna selection problem is solved by a greedy multi-start local search algorithm, and the antenna selection results of multiple target tracking are obtained. Simulation results demonstrate that the proposed algorithm can obtain a better performance in the range of subset size and targets quantity, and greatly reduce the computation complexity.
