Aiming at the problem of command and guidance countermeasure generation under new air combat conditions, a command and guidance countermeasure generation method based on the improved fireworks algorithm is proposed. Firstly, the shortcomings of the existing models are analyzed, and a support factor model is built and added. Then, considering the advantages and threats of angle, distance, speed and height, as well as the performance factors of fighter planes, a comprehensive index function is constructed. Finally, aiming at the shortcomings of the traditional adaptive fireworks algorithm in convergence accuracy and convergence speed, roulette wheel selection, dimensional variance and tabu search are applied to improving mutation operator and selection operator, and simulation analysis is carried out for the improved algorithm. The simulation results show that the improved model is more practical, the convergence accuracy and convergence speed of the algorithm are better, and it has better effect on solving the problem of air combat command and guidance countermeasure generation.
