Abstract: With the risk probability graph used to describe the air defense threat environment faced by UAV penetration, the UAV penetration problem is modeled as the optimal guidance instruction design problem, which minimizes the loss risk of UAV, and the control parameters of mission urgency and damage risk are designed. In order to solve the control model quickly, the fish swarm algorithm is further improved, so that the algorithm has adaptive step-size adjustment mechanism, and overcomes the shortcomings of the convergence speed. The results of simulation and comparative analysis show that the proposed method can make the UAV achieve penetration at a lower cost based on the urgency of mission and the importance of damage risk.
