Research on electromagnetic situation cognition for radar confrontation
-
摘要: 针对目前电磁态势认知没有形成统一认识的问题，以电磁态势中的雷达对抗态势为研究对象，提出了态势分层认知的概念，研究了雷达对抗态势知识的获取与分析，随后针对雷达对抗态势知识表示问题，建立了雷达对抗态势知识表示模型，为后续的电磁态势要素计算以及态势表征研究提供了基础。最后梳理了雷达对抗态势与电磁态势的相互关系，为下一步将雷达对抗态势融入电磁态势提供支撑。Abstract: Aiming at the problem that there is no unified understanding about the current electromagnetic situational cognition, this paper takes the radar confrontation situation in the electromagnetic situation as the research object, proposes the concept of situational layered cognition, and studies the acquisition and analysis of radar confrontation situation knowledge. To solve the problem of situational knowledge representation, the radar anti-situation knowledge representation model is established, which provides a basis for the subsequent calculation of electromagnetic situational factors and situational representation. This paper also sorts out the relationship between the confrontational situation and the electromagnetic situation, and provides support for the next step of the radar confrontation situation to adapt to the electromagnetic situation.
