摘　　要：本文分析了短波自适应跳频系统的应用状况,介绍了短波自适应跳频技术的性能特点和存在问题,提出了利用有源和无源探测技术对通信信道进行探测,以自适应实时选频的方式改进系统性能的方法,通过实地测量和对测试结果的仿真比较,证明了无源探测技术对于提高短波自适应跳频系统的抗干扰性能具有较好的效果。To improve the practicality of the HF adaptive frequency hopping system, the status of HF adaptive frequency hopping system’s application has been analyzed; the function and problem of the system have also been introduced. The methods of combining initiative detection and passive detection have been introduced in this paper, which can increase the interference rejection capability of the system. It has been proved by experiments and simulation that passive detection has done well for the adaptive frequency ...
