摘要
为更加准确灵活地运用全脉冲采样分段叠加干扰样式,对其干扰特性进行了分析。首先推导了干扰在线性调频脉冲压缩雷达匹配滤波环节的作用过程,并分析得出了干扰对匹配滤波环节的干扰特性;之后对照干扰特性分析结论,采用仿真实验定性分析、半实物实验量化分析、雷达模拟系统干扰实验效果分析的方式,进行了干扰特性分析结论的验证工作。实验结果表明,干扰的作用效果符合干扰特性的分析结论。该特性分析结论可为电磁环境模拟中相应干扰场景的构建和干扰时序的设计提供一定支撑。
In order to use the whole pulse sampling sectional stack jamming method more accurately and flexibly,its jamming characteristics are analyzed.Firstly,the action process of jamming in the matched filter of LFM pulse compression radar is deduced,and the jamming characteristics of jamming to the matched filter are analyzed;Then,according to the jamming characteristic analysis conclusion,the jamming characteristic analysis conclusion is verified by means of qualitative analysis of simulation experiment,quantitative analysis of hardware in the loop experiment and analysis of jamming experiment effect of radar system.The experimental results show that the effect of interference is consistent with the analysis conclusion of interference characteristics.Some supports for the construction of corresponding interference scene and the design of interference sequence in electromagnetic environment simulation are provided by the analysis conclusion of this characteristic.
