数据链支持下飞机敏感性评估方法研究

An Assessment of Aircraft Susceptibility under the Support of Data Link

网络中心战以信息共享和信息传输为核心。当作战飞机通过数据链得到友方共享信息后,能够更好地进行战场态势感知,从而提高自身的生存力。在这样的背景下,将飞机置于数据链支持下的作战环境中,提出了一种考虑数据链影响的飞机敏感性评估方法。首先建立了LINK11数据链与LINK16数据链的模型,得到了网络时延这种表征数据链性能的指标,然后建立了飞机对来袭导弹实施的有源欺骗式干扰模型,最后通过一个算例来评估数据链对飞机敏感性的影响。算例分析表明:数据链的时延越小,飞行员对导弹进行干扰的时间越长,干扰也就越充分,因而LINK16数据链相比于LINK11数据链更能提高飞机的生存力。但无论哪种数据链,其所带来的信息共享的优势相比于没有数据链来说还是十分明显的。通过在现有的敏感性评估模型中加入数据链影响因素,可以定量分析信息共享所带来的优势,从而对飞机生存力设计提供一定的依据。

The NCW （Net Centric Warfare） is characterized by information sharing and information transmission. When the aircraft gets the information from friendly forces, it can obtain a better situation awareness and the surviv- ability will be improved. Under this background, a method for assessing the aircraft susceptibility with the support of data link is proposed. First, the models respectively of LINK11 and LINK16 are built. The time delay reflecting the capability of the data link is obtained. Second, the active deception jamming model between the aircraft and the missile is built. At last, an example is simulated to illustrate the effect of the data link on the aircraft susceptibility. The results indicate that the shorter the time delay is, the longer the time will be left for the pilot and the jamming will be more effective. Regardless of the use of either data link , as compared with the case without data link, the advantage brought by data link is very obvious. By applying data link to the existing aircraft susceptibility model, the advantage of information sharing can be analyzed quantitatively, and the results can be applied to aircraft sur- vivability design.
