摘　　要：根据跳频频率序列的混沌特性，利用混沌时间序列的多步自适应预测算法来实现对跳频频率的多步预测，以提高预测的实时性。仿真实验说明这种多步预测方法是可行的，在一定的预测精度下可同时实现对未来多个频点的有效预测，时跳频通信预测干扰具有更好的工程应用价值。According to chaotic characteristics of FH frequency series, a adaptive multi-step adaptive prediction algorithm is engaged to predict the several frequencies of frequency-hopping communication at one time. The simulation indicated this method could effectively predict the frequencies more than one of FH communication and the result of prediction can satisfy the requisition of prediction accuracy, multi-step prediction can improve the prediction real-time ability and has practicality in the FH communication countermeasure by predicting FM frequency.
