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。
The display of the electromagnetic environment in the battlefield can truly reflect the changes of the electromagnetic environment and is of great significance to the commander’s scientific decision-making. However, there is no convenient display method at present. Combining with the basic principle of situation display, this paper presents a situation display method based on pulse flow description. This paper uses the pulse descriptor to model the RF pulse of each radiation source in the battle space, taking the typical receiver-scout receiver of electromagnetic environment as an example , The pulse stream is diluted and sequenced to generate a dense and time-varying pulse stream at the receiver. Through the statistical analysis of the time domain, the frequency domain, the airspace domain and the power domain, a comprehensive display of the electromagnetic environment in the battlefield is completed. By using this method, the situation of the typical air defense combat electromagnetic environment is displayed, which shows that the electromagnetic environment in the battlefield is time-domain intensive, overlapping in the frequency domain and power changing in a comprehensive and direct way.
