Abstract: Due to the existence of network topology switching and information transmission delay in the decentralized radar network, the global resource allocation scheme given by each radar node may be inconsistent. To solve this problem, the cooperative game theory is applied to the power allocation of netted radar nodes in multi-target tracking Scenario. Firstly, the Signal to Interference Noise Ratio(SINR) is described as a function of the target spatial position and radar transmitting power. Then, the problem of radar node power allocation in the decentralized network is regarded as a cooperative game model with SINR as the characteristic function. The weighted graph is used to improve the calculation method of the Shapley value of the cooperative game to reduce the computational complexity. A fast algorithm for solving the cooperative game model is then proposed. The proposed method does not need to use the complex optimization algorithm, and has good real-time performance. Simulation results show that the proposed method can significantly improve the target tracking performance of the netted radar.
