战场电磁环境复杂度与战术通信性能的相关性研究

目的为提升战场电磁环境环境复杂度评估的客观性,基于电磁环境与通信性能的相关性提出一种电磁环境复杂度评估方法。方法该方法以层次分析法和混合加权理论为基础,以典型通信系统为例,建立语音通信和数据通信设备性能和电磁环境复杂度等级的映射,并据此建立通信网系性能和电磁环境复杂度的等级映射,从目标层、准则层、指标层给出五级量化指标体系。结果在50 km×50 km典型地域中,上述评估方法给出了10部高频和10部超高频通信设备组成的通信网络各单链路通信质量,分别为Ⅳ、Ⅳ、Ⅰ、Ⅳ、Ⅲ、Ⅱ、Ⅳ、Ⅴ、Ⅳ、Ⅲ、Ⅱ、Ⅱ、Ⅲ、Ⅴ、Ⅱ、Ⅰ、Ⅴ、Ⅳ、Ⅴ、Ⅴ,并在此基础上评估了整个网系的通信质量等级和整个通信网系面临的电磁环境复杂度(Ⅳ)。结论上述研究验证了方法的可行性,同时证实了同一环境下不同设备所受的电磁环境影响具有个体差异性,整体通信网系的受影响程度有别于单一设备。研究结果可为通信网系的电磁环境适应性试验、电磁干扰效应评估等研究提供基础和有益的参考。

Correlation of Battle Electromagnetic Environment Complexity and Tactics Communication System Performance

Objective To improve the objectivity of evaluation on electromagnetic environment complexity of battlefield and propose a method for evaluation of electromagnetic environment complexity, based on correlation between electromagnetic en-vironment and communication performance. Methods Based on analytic hierarchy process and mixed weighted theory, with a typical communication system as an example, the mapping relation between electromagnetic environment grades and voice and data communication equipment. Based on this, the mapping relation between electromagnetic environment grades and communication network system was reconstructed to give the five-level quantitative indicator system from target level, criterion layer and index level. Results The above assessment method could respectively give the communication quality of single link of ten HF radio equipment and ten VHF radio equipment in the typical area of 50 km×50 km, the frequencies were IV, IV, I, IV, III, II, IV, V, IV, III, II, II, III, V, II, I, V, IV, V, V. On this basis, the communication quality of the whole network and the electromagnetic environment complexity (IV) were assessed. Conclusion The above research verifies the feasibility of the method and proves that influences of electromagnetic environment on different equipment in the same environment are different. The influencing degree of the whole communication system is different from single equipment. The research above provides basis and beneficial reference for electromagnetic environment adaptation test and electromagnetic interference effect, etc. of the communication system.
