在对飞行器导航优化干扰中,针对电子干扰中功率分配会影响干扰效果,采用传统的干扰功率分配方法未考虑不同目标对导航构成威胁的差异,干扰功率分配不够合理。针对上述问题,提出了一种改进遗传算法的干扰功率优化分配新方法,首先在干信比中引入威胁系数,建立干扰功率优化分配数学模型,并提出功率优化分配方案,根据敌机对导航威胁程度的不同,使用改进的遗传算法,对干扰功率进行智能分配。仿真结果表明,改进方法进行功率分配可以实现接收机处干信比均衡,为干扰功率的优化分配提供了参考。
In the optimization of aircraft navigation, the power distribution affects the interference effect in the electronic jamming. The traditional interference power allocation method does not consider the difference of different targets to the navigation, and the interference power allocation is not reasonable. In order to solve the above problems, this paper proposes a new method to improve the optimal allocation of interference power based on genetic algorithm. Firstly, the threat coefficient is introduced into the interference ratio to establish the mathematical model of optimal allocation of interference power. Different degrees, the use of improved genetic algorithm, the intelligent allocation of interference power. The simulation results show that the improved method of power distribution can achieve the signal-to-interference ratio balance at the receiver and provide a reference for the optimal allocation of interference power.
