【摘要】：在雷达抗干扰优化设计的研究中,针对雷达面临的干扰环境复杂、抗干扰作战训练难度大,以及当前雷达干扰环境仿真形式单一、干扰信号样式不完备等问题,设计了采用数字射频存储的雷达干扰环境仿真系统。在建立干扰环境系统结构的基础上,针对雷达干扰环境建模和系统模块化设计两个关键问题,采用数学建模方法构建了目标回波模型、欺骗干扰模型、无源杂波模型以及遮盖性干扰模型,采用数字射频存储技术,进行了系统的模块化设计,并对干扰环境平台进行了基于计算机仿真和半实物仿真的实际测试。测试结果表明,干扰仿真环境系统能够产生符合需求的各类样式的干扰信号,有效解决了干扰信号样式单一的问题,为检验雷达在复杂干扰环境下的工作性能创造了条件,改善和提高了抗干扰作战训练的效能。
[Abstract]:In the research of radar anti-jamming optimization design, the jamming environment is complex, the anti-jamming combat training is difficult, and the simulation form of radar jamming environment is single, the jamming signal style is not complete and so on. A radar jamming environment simulation system based on digital radio frequency storage is designed. Based on the structure of jamming environment system, two key problems of radar jamming environment modeling and system modularization design are discussed. The target echo model, deceptive jamming model, passive clutter model and shaded jamming model are constructed by mathematical modeling method. The modular design of the system is carried out using digital radio frequency storage technology. The jamming environment platform is tested based on computer simulation and hardware-in-the-loop simulation. The test results show that the jamming simulation environment system can produce various kinds of interference signals in accordance with the requirements. It can effectively solve the problem of single jamming signal, create conditions for checking the performance of radar in complex jamming environment, and improve the effectiveness of anti-jamming combat training.
