摘　　要：短波通信是一种重要的军事通信手段。为增强短波通信的抗干扰性能和可通率,提出了一种跳频自适应控制方案。该方案给出了基于同步探测扫描的非对称跳频频率选择协商机制,提出了跳频频率个数自动调整,以及针对各跳频频率质量差异采用的分频率快速速率自适应策略。本方案在原理样机上进行了实现,并进行了线路试验。试验表明,该控制机制能有效地躲避干扰,较好地提升短波通信效果。HF(High Frequency)communication is an important means of military communication.In order to enhance the anti-interference and traffic ability of HF communication,a frequency hopping adaptive control scheme is proposed.The scheme gives an asymmetric hopping frequencies selection negotiation mechanism based on synchronous detection and scanning,and proposes automatic adjustment of the number of frequency hopping frequencies,and a fast rate adaptive strategy of each frequency based on the quality of the frequency hopping.This scheme is realized on the principle prototype,and the field test is also carried out.Experiments indicate that the control mechanism can effectively avoid interference and improve the effect of HF communication.
