Abstract

Abstract:

Based on the distributed MIMO radar systems, transmitted power and signal bandwidth are jointly allocated to improve the tracking accuracy for a maneuvering target when the resource is limited. Firstly, the Bayesian Cramer Rao Bound (BCRLB) for the maneuvering target tracking error is deduced. Then, a criterion for minimizing the BCRLB is derived, and the corresponding optimization problem with two independent vectors is solved by the cyclic minimization algorithm together with convex relaxation and convex optimization. Simulations demonstrate that the tracking accuracy is improved by the proposed algorithm.

Key words: distributed MIMO radar, maneuvering target tracking, power allocation, bandwidth allocation
