基于混合优化算法的正交多相码的设计

通过结合模拟退火算法的概率接受准则和蚁群算法的并行搜索，提出了一种有效的混合优化算法，设计出了具有良好自相关和互相关性能的正交信号组。混合算法弥补了模拟退火算法的搜索效率低和蚁群算法的容易陷入局部最小值的缺点，提高了全局搜索的能力。仿真结果表明，在搜索最优正交多相码方面该混合优化算法优于其他搜索算法。

Polyphase Orthogonal Code Design Based on Hybrid Optimization Algorithm

By combining the probabilistic acceptance property of Simulated Annealing(SA) algorithm with the parallel searching structure of Ant Colony(AC) algorithm,an effective hybrid algorithm is proposed to design ployphase coded signals for orthogonal netted radar systems.The simulation results show that the hybrid algorithm compensates the demerits of AC that is easy to be run into local optimum and SA that has lower efficiency,and strengthen the global search ability.Comparing with other algorithms,the proposed algorithm has better performance to design ployphase orthogonal code.
