复杂电子系统可测性建模方法研究

Researching on method of modeling complex electronic system for testability

通过比较电子系统建模方法,提出基于多信号模型的可测性建模方法。以典型的电子系统雷达发射机为例,详细介绍可测性建模方法,通过模型得到该系统的故障测试依赖矩阵,为复杂电子系统进行可测性分析提供了条件,同时也为雷达系统故障诊断提供依据。

Based on comparing each methods of modeling electronic system, this paper proposed a method of modeling elec- tronic system based on multi-signal model. Used a typical electronic system-radar transmitter to demonstrate concrete steps for testability model, attained the relation matrix of faults and tests in the system. The proposed method provides not only the con- dition for analyzing complex electronic system testability but also offer a basis for fault diagnosis of radar system.
