摘要
随着无人机在现代战场与民用领域中的飞速发展,数据通信的可靠性、有效性、及时性和隐蔽性等要素也被提出了更高的要求。时延是无人机通信质量中最重要的性能指标之一。通过对时延的组成与数据链基本特性的研究,首先介绍了2种曾广泛使用的数据链时延测试方法。随着无人机数据链设备集成度越来越高,数据链协议越来越多样化,以往的测试方法已经不再适用。针对目前遇到的问题,提出了一种基于高精度时间计数器的、更具有通用性、准确度更高的新测试方法,并对测试流程和处理时序进行了研究。经过软件实现、工程实践和验证,证明测试方法可行,测试结果可信,为数据链指标测试方法的标准化提供了支持。
With the rapid development of UAV in modern battlefield and civil field,there are higher requirements for the reliability,effectiveness,timeliness,concealment and other elements of data communications.Delay is one of the most important performance indexes of UAV communication quality.By studying the composition of delay and the basic characteristics of the data link,two widely used methods of the data link delay test are firstly introduced.With the increasing integration of UAV data link equipments and the increasing diversification of data link protocols,the previous test methods are no longer applicable.In order to solve the current problems,a new test method based on high-precision time counter with higher universality and accuracy is proposed,and the test process and processing sequence are studied.Through software implementation,engineering practice and verification,the test method is feasible and the rest results are reliable,providing support for the standardization of data link index test method.
