摘　　要：由于认知无线电自身具有环境感知能力和学习重构能力,该项技术的应用给通信对抗提出了新的挑战。面对具有认知能力的终端,传统的粗放式的干扰方式不仅造成干扰功率的浪费,同时容易使自身暴露在敌方的雷达扫描之下而被摧毁、打击。因此,如何既能够有效地干扰目标认知终端,同时也能够较好的保全自己显得尤为重要。文中提出了一种基于认知终端抗干扰门限的灵巧干扰的观点,通过使用一种快速的查找算法获得目标认知终端的抗干扰门限值,以此作为干扰机发射的干扰功率,从而实现灵巧干扰。The application of cognitive radio（ CR） brings new challenges to communication countermeasures due to its environment perception ability and learning reconstruction ability. Faced with cognitive terminal,traditional extensive interference patterns not only lead to the waste of jamming power,but also easily expose itself to the radar detection of enemy and then are destroyed totally. Therefore,how to interfere with target cognitive terminal and better protect it from being destroyed is of utmost significance. Thus,an idea of smart jamming based on anti-interference threshold of cognitive terminal is proposed in this paper. With this proposed idea,a fast search algorithm to exactly acquire the anti-interference threshold of cognitive terminal is adopted,which can be used as the interference power of jammer,thus to achieve the goal of smart jamming.
