The invention discloses a co-location MIMO radar robust power distribution method in multi-target guidance under a suppressing interference background, and the method comprises the following steps: S1, constructing a co-location MIMO radar system model under an active suppressing interference background; s2, performing real-time estimation on the target state by adopting a PSCKF algorithm; s3, deducing the mutual information (MI) and taking the MI as a tracking performance index; s4, by predicting the MI, establishing an optimal distribution model about the transmitting power; and S5, solving the optimization model by using a BCR-based two-step solving method, and feeding back a solving result to the radar system to guide the emission work at the next moment. Finally, while the number of effective tracking targets is increased, the overall tracking precision of the targets is improved. 本发明公开了一种压制式干扰背景下多目标制导中的共址MIMO雷达稳健功率分配方法，包括以下步骤，S1：构建有源压制式干扰背景下的共址MIMO雷达系统模型；S2：采用PSCKF算法对目标状态进行实时估计；S3：对互信息(MI)进行推导并将其作为跟踪性能指
