摘　　要：针对北斗/INS组合制导系统易受干扰等问题,设计了神经网络辅助的抗干扰方法。分析了压制式和欺骗式干扰的特点;设计了抗干扰系统的工作流程;通过设计干扰检测统计量和判断准则,建立了神经网络辅助的干扰检测算法;根据天线阵列原理,设计了自适应调零天线抗干扰方法。仿真实验表明神经网络辅助的干扰检测算法对干扰比较敏感且虚警率较低,能有效地对干扰进行检测;利用训练好的神经网络输出的预报值对导航解进行修正,具有较高的精度。In order to overcome the shortcomings of compass/INS integrated navigation system, a neural network aided anti-interference method was established. The characteristics of suppression interference and deception interference were analyzed, the working flow of antijamming system was designed, neural network aided interference detection algorithm was built by designing interference detection statistics and criterion; Antenna hulling anti-interference method was designed based on the principle of antenna array. Simulation experiment confirms that neural network aided interference detection algorithm for interference detection is sensitive and with low false alarm rate, it can effectively detect interference ; There is high precision when the forecast output value of the trained neural network is used to correct navigation information.
