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。
According to the complex jamming environment that radar faces, the difficulty of anti -jamming com- bat training, the single form of current radar jamming environment simulation and the imperfection of jamming signal styles, a simulation system of radar jamming environment based on DRFM was designed. Based on the establishment of the system structure of the jamming environment, and according to the two key problems of radar jamming environ- ment modeling and system modularized designs, target echo, deception jamming, passive clutter and masking jam- ming models were constructed using mathematical modeling methods, and modularized designs of the system was solved based on DRFM. Besides, actual test of the jamming platform based on computer simulation and semi - physi- cal simulation was carried out. The test results show that this jamming simulation environment can meet the needs of all kinds of required jamming signals. It solves the problem of single form of jamming signals effectively, creates con- ditions for the inspection of radar performances in the complex jamming environment, and improves the efficiency of anti - jamming combat training.
