面对样式捷变雷达信号,传统雷达侦察信息处理技术在干扰保障过程中存在实时性、快速性等适应能力不足的问题。文中提出了一种基于脉冲描述字(PDW)快速跟踪的雷达侦察信息敏捷处理技术,通过建立PDW快速跟踪处理通道和处理模型,基于少量脉冲PDW实现对辐射源参数变化的快速跟踪和干扰信息引导,提升对脉组频率捷变、自适应抗干扰跳频等雷达参数捷变的敏捷感知和跟踪能力。通过数字仿真验证了所提方法的技术有效性。

The traditional radar reconnaissance information processing technology has the disadvantages of insufficient adaptability on real-time requirement and rapidity in the process of interference guarantee when applied to agile radar signals. An agile processing technology for radar reconnaissance information based on pulse description word (PDW) fast tracking is thereby proposed in this paper. By establishing PDW fast tracking processing channels and processing models, a few of PDWs are applied to achieve fast tracking and interference information guidance for the changes of radiation source parameters, and improve the agile sensing and tracking capabilities of dealing with agile radar signals such as pulse-train frequency agility, adaptive anti-jamming frequency hopping, and so on. The effectiveness of proposed technology is verified by digital simulation.
