To solve the problem of how to detect and isolate the fault of radar system with low test cost, a design method of diagnostic strategy for radar system based on rollout algorithm is proposed. This method takes the greedy search method based on information heuristic as the benchmark strategy, and uses the rollout strategy to iterate on the benchmark strategy, so as to overcome the problem of poor optimality of greedy search method. Taking the radar system dependency model as an example, this paper uses rollout algorithm to generate the diagnostic strategy of the radar system, which verifies the effectiveness of the method.
