摘要: 为在战场电磁环境下进行科学分配频率,减少各部队用频设备之间的相互干扰,提出一种基于混沌扰动机制粒子群算法的频率分配方法,将战场频率分配转化为带约束条件的最优频谱资源查找求解问题,建立以干扰代价最低为目标的频率分配模型,通过改进的粒子群算法进行频率分配该算法引入混沌扰动机制,提高种群多样性和算法全局寻优能力,避免算法陷入局部最优。通过实验表明,在频率分配过程中该算法是可行的,并且其收敛性和解集的多样性均明显优于粒子群算法。

Abstract: In order to carry out the frequency allocation in the electromagnetic environment of battlefield and reduce the frequency equipment interference of various forces, a frequency allocation method based on chaotic perturbation mechanism particle swarm optimization algorithm is proposed. Which transforms battlefield frequency allocation into the optimal spectrum resource search and solution problem with constraints. The frequency allocation model with the lowest interference cost is built and the frequency allocation through the improved particle swarm optimization algorithm is carries out. The chaotic perturbation mechanism is introduced to improve the population diversity and the global optimization ability of the algorithm, which avoids the algorithm falling into the local optimization. Experiments show that the algorithm is feasible and the convergency and diversity of the solution are obviously better than those of particle swarm optimization algorithm.
