多站雷达功率分配自修正凸松弛算法
Auto-corrected convex relaxation algorithm for power allocation in multi-radar system used as target localization
摘要
Abstract
To improve the radar performance under limited transmit energy,this paper improves a power allocation algorithm for the distributed multi-radar system.First,the Cramér-Rao Lower Bound(CRLB) of the target localization mean square error(MSE) of the distributed multi-radar system is given in this paper, and can be used as a suitable cost function to perform the power resource allocation.Then,in order to be close to the optimal solution,this paper improves the classical convex relaxation methods.We make full use of the limited resources multi-radar system to approximate the optimal result by the auto-correct convex-relaxation parameter to reduce the extra error caused by the convex relaxation process.Finally,simulation results prove that the proposed algorithm is effective.关键词
