摘要
雷达信号脉内调制类型与调制参数是脉冲信号分选与识别的关键信息之一,在电子侦察中发挥着重要作用。在对雷达脉内调制的分类概要介绍之后对其发展历程进行了简要回顾,在此基础上从简单调制、复合调制与新型调制三个方面对雷达脉内调制的数学模型与脉冲描述字表征方法进行了详细的归纳总结,指出了雷达通信一体化波形设计给电子侦察所带来的全新挑战,同时也反映了雷达侦察与通信侦察融合发展的必要性与紧迫性,指引了电子侦察技术的新的发展方向。
The types and parameters of radar intra-pulse modulation are significant information for pulse signal de-interleaving and recognition. It plays an important role in electronic reconnaissance. After a brief introduction of the radar intra-pulse modulation classification, the development history of radar intra-pulse modulation is briefly reviewed. Then, the mathematical model of radar intra-pulse modulation and the representation of PDW(Pulse Descriptor Word) are summarized in detail from three aspects about simple modulation, compound modulation and new modulation. The new challenges from the integrated waveform design of radar and communication to electronic reconnaissance are pointed out. At the same time, it reflects the necessity and urgency of the integration of radar reconnaissance and communication reconnaissance, and it is also a new technical development direction of electronic reconnaissance.
