短波通信由于通信距离远、顽存性强等优点而广泛应用于军事通信领域。为增强短波组网通信的抗干扰性能，将信道感知技术与短波组网相融合，提出了一种基于协作感知技术的网络频率自适应技术。该技术在初始组网时，能正确、快捷的从频率库中选出适用于整个网络的最佳工作频率；在网络运行过程中，根据频率的质量变化情况，及时地调整工作频率。 OPNET仿真表明，该协作感知技术有效，对通信性能改善明显。

HF ( high frequency) communication is widely used in military communication for its advantages of long-distance communication, strong survivability and so on. In order to enhance the anti-jamming per-formance of HF networking,and by integrating channel sensing technology and HF networking,an adaptive technique of network frequency based on cooperative spectrum sensing is proposed. The proposed tech-nique can quickly and correctly select an optimum frequency from frequency lab in the initial phase of net-working and apply it to the entire network. And in the process of network operation, it can adjust the work frequency according to the quality variety of frequency. OPNET simulation shows that this cooperative spectrum sensing technique is effective and could obviously improve the communication performance.
