摘要
针对电子对抗侦察领域对截获雷达信号认知的需求,对雷达信号基因的形成机理和建模问题进行研究。首先,分析了雷达信号的不同层次和层次之间的转化关系,将雷达信号划分为脉冲层、脉冲群组层、工作方式层三个层次;然后,借鉴生物体基因工程中蛋白质、DNA、基因片段的概念,类比对应雷达信号的不同层次信息,提出了雷达信号基因的概念和层次模型,建立了雷达信号层次处理的研究框架;最后,针对当前新体制雷达的典型信号,给出了雷达信号脉内基因的表征实例。
Aiming at the cognizance demand for intercepted radar signals in the field of electronic countermeasures reconnaissance, the formation mechanism and modeling of the radar signal genes are studied. Firstly, the different levels and transformation relations between different levels of radar signals are studied, and the radar signals are divided into three levels: pulse layer, pulse group layer and working mode layer. Then, reference proteins, DNA, gene fragment of biological genetic engineering, the concept of analog information corresponding to the different levels of radar signals, the concept of radar signal gene and the hierarchical model are proposed, and the radar signal level processing research framework is constructed. Finally, aiming at the typical signal of the new system radar, a representative example of the radar signal intra-pulse information gene is given.
