Abstract:

A cooperative coverage guidance method for multiple missiles region based on interception probability is proposed to address issues of significant ballistic dispersion and differences in missile interception regions in long-range air defense multiple missiles cooperative interception missions with the condition of low-accuracy. Firstly, a nonlinear fitting of the miss distance probability distribution obtained by Monte Carlo simulations is performed to establish an interception probability model for interception coverage regions. This model serves as a coverage node in the regional coverage optimization problem, with the highest regional interception probability as the coverage optimization criterion. Secondly, an improved Circle and Tent mapping hybrid strategy adaptive particle swarm optimization (CT-HAPSO) regional coverage algorithm is designed. The proposed algorithm optimizes the allocation of interception region of each missile within the target error region. The allocated node positions are used as the midcourse guidance points for each missile. By merging high-probability interception regions and low-probability overlapping interception regions, the overall high-probability interception region is expanded, improving the overall interception probability of coverage region. Finally, the effectiveness of the proposed method is verified through guidance simulations in a three-dimensional scenario.

Key words: interception probability, cooperative coverage, target error region, particle swarm optimization (PSO) algorithm
