STANAG 7023标准介绍与应用研究

摘要

This paper introduces the STANAG 7023 standard that is a data multiplexing standard used in military to handle words and image data.The standard add categories to identify, time stamp, check code and so on to multiplexes the data into packets,arranges the packets as segments then arrangees the segments as record finally.The disadvantage of this standard is low efficiency for multiplexing the auxiliary information. The multiplexing efficiency of less than 15% when using the five kinds of common auxiliary information which the average length is 28. This paper improve the multiplexing efficiency to 48.3% by using the mathod which is the combination of variable length frame and fixed length frame.%STANAG 7023标准是一种军事领域使用的数据复接标准，用于处理文字与图像信息。这一标准通过添加分类标识、时间戳、校验码等冗余信息将信息复接数据包，再将数据包排列为数据段，最后将数据段排列成数据记录，完成复接的功能。在实际使用中，这一标准的缺点是针对辅助信息的复接效率非常低。选取平均长度为28字节的五种常用的信息做复接时，复接效率不足15%。针对这一缺陷，本文利用定长帧与变长帧结合的思想，改进复接方案，将辅助信息复接效率提高到48.3%，提高了信息的复接效率。
