To meet the need of the real application, this paper proposes a power allocation algorithm for multiple target localization, which tries to get the quick optimal allocation of the limited power resources in the MIMO radar. Firstly, Cramér-Rao Lower Bound (CRLB) of the Mean Square Error (MSE) of the multi-target localization is given, and CRLB is used as a cost function to allocate the power resource. Then, an Alternating Global Optimal Algorithm (AGOA) is designed which can be used in power allocation of multi-target localization, the related Pareto sets to achieve the fast allocation of the power resources. Finally, the simulation results show that the AGOA can quickly achieve the optimal allocation of the limited power allocation in MIMO radar, and can significantly enhance the precision of the multiple target localization.
