基于脉冲流描述的战场电磁环境态势显示方法

Situation Displaying of Battlefield Electromagnetic Environment Using Pulse Flow Description

战场电磁环境态势显示可真实地反映电磁环境变化,对指挥员的科学决策具有重要意义,但目前缺乏便捷的显示方法。结合态势显示的基本原则,提出一种基于脉冲流描述的态势显示方法:以电磁环境的典型受体-侦察接收机为对象,利用脉冲描述字对作战空间内各辐射源的射频脉冲进行建模,通过对脉冲流进行稀释和排序,生成接收机处密集而时变的脉冲流,经过时域、频域、空域、功率域等的统计分析,完成战场电磁环境态势的综合显示。应用本方法,实现了典型防空作战电磁环境的态势显示,全面、直观地反映出战场电磁环境的时域密集、频域交叠、功率多变等态势。

To reflect the dynamic process of decision-making battlefield electronmagnetic environment （ BEME）, situ- ation displaying （SD） plays an important role in decision-making in warfare. A combined displaying approach of BEME based on pulse flow description is proposed for the lack of convenient situation description. The fundamentals of SD were ana- lyzed, while the reconnaissance receiver was chosen as a typical reception of BEME. The constituent radiant sources in space were sorted, and the pulse description word （PDW） models were established to obtain their own radio frequancy pulses, which were dynamically combined by pulse dilution to generate a dense and changing stream in the receiver. The situation of BEME was then displayed according to statistics of pulse stream in time, frequency, and power domain. Situation maps in a specified aerial defence warfare secnario were provided to reveal the situation of denseness in time, overlap in frequancy as well as inconstancy in power completely.
