简介了故障树技术的原理和CINRAD-C气象雷达BIT系统的组成。从总体设计的角度出发，着重对全机故障分配的确定、雷达故障树的建立和故障树的算法的实现等方面进行了阐述，为实现雷达的BITE起到促进作用。指出了该系统进一步完善所面临的尚待解决的问题。

This article introduces briefly the principle of FAT and configurations of CINRAD-C weather radar's BIT system. From the system design view point ,it describes how to establishing the radar fault's distribution, create FTA and realize FTA's arithmetics by software in aiming to promote the realization of radar's BIT system. Finally, it points out the problems that need to be solved for improving this system. [
