Abstract:

Aiming at the problem of learning unknown dynamic interference patterns, a frequency point cooperation algorithm for radar and communication anti-interference based on kernel function reinforcement learning is proposed. On the contrary, the proposed algorithm can optimize the anti-interference frequency allocation strategy by using the usage of the intermediate frequency points in the past slots. Firstly, the problem of curse of dimensions is solved by reinforcement learning of kernel function. Secondly, the online kernel sparsity method based on approximate linear correlation ensures the sparsity of anti-interference frequency assignment algorithm. Finally, simulation results verify the effectiveness of the proposed algorithm. Due to the learning of sparse codewords for the dynamic characteristics of the system, compared with the traditional anti-interference frequency assignment algorithm based on Q-learning, the proposed algorithm has shorter convergence time and can quickly avoid the interference of external unknown interference sources.
