雷达数字电路板故障测试技术研究

Fault testability technology of digital circuit board for radar

现代军用电子设备大量采用各种大规模和超大规模集成电路和电子计算机,使其本身变得日益复杂,给使用、维修和保障带来很多严重问题。在这种情况下,研究故障诊断和测试技术就显得十分重要。介绍了一种雷达数字电路板的可测试性设计方法,包括设计采取的措施、测试性工作流程、测试性的工作内容。该技术已经成功应用多种雷达数字电路板故障测试中,效果明显。

Modern military affairs are becoming more and more complex for all kinds of large scale integrated and grand scale integration circuit are used. Therefore, a great many problems such as useability, maintain and indemnificatory were come to bing. In this instance, the search of the fault diagnosis and testability technology is very important. In this paper the testablity technology of digital circuit board for radar is summarized. The design principle, research content and work flow for testability, are introduced in detail. The fault testability technology has been applied in many kinds of digital circual board for radar.
