基于角度欺骗的编队协同探测与干扰技术

The advanced air defense systems carried on the aircraft, ground-base and ship platforms have the advantages in active detection and passive reconnaissance with network connection. These systems are the severe threat to our penetration formation. Because the angular information fusion and across location techniques can provide the steady target tracking under the countermeasure conditions, they have been an useful method in the advanced air defense systems. The breakthrough techniques of nowadays are invalid for these advanced systems..The radar detection and jamming techniques with angular deception function are the most effective method to countermine the angular information fusion and across location in the air defense systems. Therefore, they have an important academic significance and application value. On the background of coordinated attacking of penetration fighter formation, this project will offer significant reference to enhance the integrated countering capability of penetration formation. Firstly, according to the electromagnetic theory and radar signal theory, the characteristics of angular deception using multiple coherent point sources will be studied. Secondly, based on the characteristics of angular deception, the complicated signal processing technique for distributed cooperative detection and the stand off angle deception technique for cooperative jamming will be investigated. The achievements of this project will offer significant reference for the realization of radar detection and jamming techniques with angular deception functions.

先进防空系统以机载、地基、舰载平台为基础，具有网络化的有源探测与无源侦察能力，是我突防编队面临的主要威胁。测角信息融合与交叉定位由于能够在对抗条件下稳定跟踪目标，已成为先进防空系统一种极为有效的技术手段，现有突防对抗方法不能够应对。研究具有角度欺骗能力的雷达探测和雷达干扰技术，是应对防空系统测角信息融合与交叉定位的最有效手段，具有重要的学术价值和应用前景。本项目以突防飞机编队协同作战为背景，首先，通过电磁学理论和雷达信号理论的结合研究相干多点源角度欺骗的特性，继而，以之为基础，突破分布式协同探测中的信号处理技术和分布式协同干扰中的远距离角度拖引干扰技术，进而为实现具有角度欺骗能力的雷达探测与雷达干扰提供重要支撑。

空间分布式系统能够破坏雷达或雷达侦察系统的角度测量，在未来雷达电子战技术发展中具有重要的地位。项目研究聚焦于“空间分布式多点源对角度测量的影响效应”，通过开展暗室测量实验支撑了多点源合成特性建模的研究，通过构建雷达对抗仿真平台支撑了多点源对雷达测角影响效应的研究，在此基础上开展了分布式协同探测与分布式协同干扰技术的攻关，分别提出了波形与信号处理设计方法以及干扰参数设计方法，研究过程涵盖理论分析、测量实验、关键技术研究，研究成果能够为分布式雷达探测与干扰技术提供基础支持。
