Power allocation for multiple targets localization in distributed MIMO radar system

To improve the resource utilization for MIMO radar system in multiple tasks model, a power allocation algorithm is proposed for multiple targets localization. The Cramer-Rao bound (CRB) is used to be the measurement metric for location estimation. The minimal transmit power budget is used as the cost function. Restricted by different localization mean square error (MSE) requirements, a power allocation model is established, and the corresponding optimization problem is solved by Sequential Parametric Convex Approximation (SPCA) algorithm. The simulation results indicate that under different system layout and target Radar Cross Section (RCS), the proposed allocation algorithm can improve the resource utilization by using much less power budget than uniform allocation.
