雷达武器装备数字电路测试诊断技术研究及改进

Technological Research and improvement of Test and Diagnosis for Digital-Circuit on Radar Arms

以雷达武器装备数字电路维修保障为背景,分别从故障来源、测试系统类别等对方面国内外主流的数字电路测试诊断技术进行了研究,并在详细分析ICT(In-Circuit)测试、功能测试及传统边界扫描测试原理的技术上,对传统意义上的边界扫描测试诊断技术进行了改进,提出了"MERGE"边界扫描测试模型建立方法,拓展了边界扫描技术的适用范围,解决了对含有大规模集成电路的新型雷达装备数字电路的测试问题,其整体研发思路对同类型测试诊断平台的研发具有重要的借鉴价值和参考意义。

In the background of maintenance of the digital circuit of Radar Arms,researching the domestic and overseas test and diagnosis mainstream technologies for digital circuit from fault sources,sorts of test system and so on,improving the traditional Boundary-Scan Testing Technology and providing a'MERGE'method to build the Boundary Scan models based on analyzing particularly the ICT(in Circuit Testing),functional Testing and traditional Boundary-Scan Testing.The'MERGE'method not only expanding the applicability of Boundary-Scan testing,but also solving the test problems met on the new-style radar arms' digital circuit contained LSI(Large Scale Integrated circuit)on.The totally idea have great reference worthiness and significance for further research of the other kindred test equipments.
