摘　　要：在信息化战场上,各作战要素效能的发挥直接依赖于相互之间的通信与协同,而面对日益匮乏的频谱资源及愈来愈恶劣的战场电磁环境,及时有效的无线通信日益成为亟待解决的问题。认知无线电技术作为一种智能无线电技术,可赋予军用无线通信系统以电磁环境感知能力,有效解决频谱资源的利用和管理问题,提高通信系统的抗干扰性能。文中概述了军用认知无线电的基本概念、认知循环模型、待解决的关键技术,提出了下一步军用认知无线电的研究方向,最后探讨了军用认知无线电给军用电台结构带来的变化。The performance of battle elements in information warfare depends greatly on the communication and cooperation among them. With the exhaustion of spectrum resources and the disadvantages of electromagnetic environment, real-time and valid wireless communication becomes a serious problem which should be solved. As an intelligent wireless communication technology, cognitive radio can sense electromagnetic environment and resolve the utilization and management of radio spectrum resources. Moreover, the anti-jamming performance of wireless communication system is enhanced. The conception of Military Cognitive Radio （MCR） was introduced, as well as cognitive circulation model and immediate technical issues. And the further research of MCR and the changes caused by MCR in military broadcasting station were also discussed.
