Cooperative game-based cooperative MIMO radar communication integrated system power distribution method

The invention discloses a cooperative game-based power distribution method for a cooperative MIMO radar communication integrated system, and belongs to the field of communication. According to the power distribution method of the cooperative MIMO radar communication integrated system, under the Neyman-Pearson criterion, the target detection probability serves as a radar performance evaluation index, and the communication mutual information amount serves as a communication performance evaluation index. In the method, a radar subsystem and a communication subsystem are regarded as two parties of a cooperative game, and an optimization problem based on a Nash bargaining solution is established by considering that the total power of the system is limited. According to a cooperative game theory, a Nash bargaining solution obtained by using an iterative NBS algorithm meets the properties of Pareto optimality, fairness and the like. The iterative NBS algorithm may adjust whether the system performance is more tendin
