摘　　要：针对对空情报雷达,在分析现有雷达对复杂电磁干扰环境感知能力不足和干扰抑制效果不理想现状的基础上,增强雷达对电磁环境的主动学习能力,实现智能化抗干扰处理流程。根据复杂电磁干扰环境以及探测任务需求,首先实现干扰环境的自适应感知,然后重点突破抗干扰各环节的智能决策技术,最终实现抗干扰流程的组织协同进化。在干扰感知方面,采用核方法和原子分解等新技术完成干扰环境的态势感知。在干扰抑制方面,采用动态环境盲分离、波形设计与优化和空域-极化域联合处理等技术完成有源干扰智能化抑制。For the air intelligence radar,the existing jamming sensing ability of the radar is not enough in the complex electromagnetic interference environment,and the existing jamming suppression effect is not satisfactory with the need.Based on the analysis of current research situation,it is necessary to enhance the ability of radar active learning to the electromagnetic environment,and realize the intelligent anti-jamming processing process.According to the requirements of the complex electromagnetic interference environment and the detection mission,the adaptive sensing of the jamming environment is realized,and then the intelligent decision techniques in all aspects of anti-jamming are proposed.Finally the organization co-evolution techniques of the anti-jamming processes are achieved.For the jamming sensing,the new techniques such as the kernel-based methods and atomic decomposition are used to complete the situation awareness of the interference environment.For the jamming suppression,the new techniques of the dynamic environment blind separation,the waveform design and optimization,and the joint processing of spatial-polarization domain are chosen to achieve the jamming intelligent suppression.
