摘要: 宽带信号具有较好的抗干扰性能和反对抗能力, 但要在鱼雷电磁引信上实现工程应用仍有许多问题亟待解决, 宽带直接耦合干扰的快速、有效补偿问题即是其中之一。文中分析研究了鱼雷宽带电磁引信直接耦合干扰的特征, 提出了一种快速、有效的宽带直接耦合干扰补偿方法。该方法采用Butterworth低通滤波器传递函数对递推最小二乘算法的遗忘因子迭代更新模型进行改进, 解决了标准算法在对突变信号的快速跟踪性能与低稳态误差特性上的矛盾。将改进算法分别应用于跳频和调相2种宽带体制下鱼雷电磁引信直接耦合干扰的自适应补偿中, 并进行了仿真分析。仿真结果表明, 文中改进的自适应算法对突变信号具有较好的跟踪性能和较低的稳态误差, 能够实现对跳频体制和调相体制鱼雷宽带电磁引信直接耦合干扰的快速、有效补偿。Abstract: Wideband signal has anti-interference and counter-countermeasure properties. However, engineering application of wideband signal to torpedo electromagnetic fuze still faces many problems, including fast and efficient compensation of wideband direct coupling interference. In this paper, the characteristics of direct coupling interference of torpedo wideband electromagnetic fuze are analyzed, and a fast and efficient compensating method for wideband direct coupling interference is proposed. The transfer function of Butterworth low filter is used to modify the iterative updating model of forgetting factor in recursive least squares algorithm. The modification resolves the contradiction between the ability of singular signal fast tracking and the low steady state error. This method is applied to adaptive compensation of direct coupling interference of torpedo electromagnetic fuze with two wideband signal systems of frequency hopping and phase modulation, respectively. Simulation analysis shows that the improved adaptive algorithm has better tracking performance of singular signals with low steady state error. The proposed method could realize fast and efficient compensation of the direct coupling interference in the wideband signal systems of frequency hopping and phase modulation, respectively.
