基于“OODA环”优化的卫星导航定位安全与对抗应用研究

Research about Application of OODA Ring Optimization in Satellite Navigation and Positioning Security and Countermeasures

摘要:

卫星导航定位设备的“生存”环境日益复杂、严峻，各类电子对抗、干扰欺骗十分激烈，人为干扰已成为卫星导航定位安全与对抗的重点。针对传统手段无法有效应对干扰复杂性、全面性、系统性的不足，本文在分析“OODA环”理论和实践转化的基础上，结合复杂环境下“干扰-抗干扰”的整体对抗过程，优化“OODA环”运行，将其与卫星导航定位安全与对抗应用进行耦合，提出基于“环境感知-筛选隔离-检测识别-效能评估-策略规划-对抗反制-回访反馈-再感知”的卫星导航定位安全与对抗不定向循环链路，并对拓展、映射的七个环节及关键技术进行分析、论证。通过引入“循环”和“不定向”两个概念，不仅实现了周期性外循环和部分环节内循环的嵌套迭代和导向性传输的运行机制；而且优化了内循环的自由度，使得各环节互联且独立、循环但不定向，有效增强了卫星导航定位安全与对抗的鲁棒性。本文的设计思路可加快实现循环链路的动态闭环，提高对抗的整体效能，在实践应用和技术论证中具有一定的参考价值。

Abstract:

The living environment of satellite navigation and positioning equipment is increasingly complex and severe,all kinds of electronic countermeasures,interference and deception are very fierce,and man-made interference has become the focus of satellite navigation and positioning security and confrontation. In view of the shortcomings of traditional means to effectively deal with the complexity, comprehensiveness and systematization of interference,the paper ,based on the analysis of OODA ring theory and practice transformation, combined with the overall counter process of interference and anti-interference in complex environment, optimized operation, coupled with satellite navigation and positioning security and counter, innovative satellite navigation and positioning security and counter non-directional circular link which is based on environment awareness, screening isolation, detection and recognition, performance evaluation, strategic planning, counter attack-return visit feedback, reperception. The seven links of expansion and mapping are analyzed and demonstrated. By introducing the concepts of loop and undirected, the operation mechanism of nested iteration and guided transmission of cyclic outer loop and loop in link is not only realized, but also the freedom of the inner loop is optimized, so that links are interconnected and independent, and loop but not directed, effectively enhance the safety of satellite navigation and positioning and the robustness of confrontation.The design idea of the paper can accelerate the realization of the dynamic closed-loop loop of cyclic link, improve the overall efficiency of countermeasure, and has certain reference value in practical application and technology demonstration.
