摘要
针对测控新体制在运行中出现的新问题,本文提出利用跳频图案稳定性及跳频增益稳定性两项新指标来完善现有测控系统测试体系;分析了两项指标在测控系统测试中的新颖性及重要性;从定性与定量两方面定义了指标的含义;研究了指标的测试方法,并针对跳频图案稳定性测试结果出现的误差提出了修正算法;最后研究了测试结果的多种可视化显示技术。分析及仿真结果表明,测试指标有效地表征了测控新体制运行中出现的新现象,测试方法能准确完成指标的测试,可视化方案可以多角度直观地显示测试结果。
In order to solve the unprecedented issues during the TT＆c system running, two fresh indicators named the stability of the hopping pattern and the stability of frequency hopping gain were presented. The indicators can improve the test system of TT＆C. The novelty and importance in testing of TT＆C were analyzed; the meaning of the indicators from both qualitative and quantitative aspects was defined; the test method of the indicators was provided, and a new algorithm used to correct the test error about the stability of the hopping pattern was proposed. At last, a variety of visualization technologies were studied. The analysis and simulation resuhs show that the indicators can describe the phenomenon effectively in the system, the methods can accurately complete the test and the visualization scheme can show the test results from different visions.
