| 摘 要： | 首先分析混频输入级高频地波雷达中短波通信干扰的特征,借鉴用基于LMS算法的自适应滤波方法抑制短波通信干扰的处理思想,通过构建基于Hopfield神经网络的自适应滤波器来抑制短波通信干扰.通过仿真比较这两种自适应滤波器的处理效果,验证了用基于Hopfield神经网络的自适应滤波来抑制短波通信干扰方案是可行的.

| Abstract: | By analyzing the properties of shortwave communication interferences (SCI) in high frequency surface wave radar, especially the properties of SCI at the mixing input site in the receiver, a method of exploiting the adaptive filter based on Hopfield neural network (HNN) to suppress SCI is proposed in this paper. Compared with the adaptive filter based on LMS (least mean square) algorithm, the simulation results show that the feasibility of the method based on HNN scheme for suppressing SCI in high frequency surface wave radar. |
