摘　　要：针对某相关干涉仪测向系统验收过程中出现的问题，首先根据相关干涉仪测向原理，对该系统在低频段测向精度低于产品指标要求的现象进行了分析，初步找出了产生故障现象的原因；其次在实验室对故障现象进行了仿真演示，确定了故障部件；最后对系统进行了优化设计，并进行了外场试验验证，切实提高了该系统的性能。Considerring the problem of the correlative interferometer system that occured during the military inspection and acceptance, this paper firstly analysed the phenomenon of the unideal phase accuracy error in the lower frequency band according to the theory of correlative interferometer direction finding （DF）, and found out the reason that brought about the phenomenon. Secondly, the fault phenomenon was simulated and demonstrated in the laboratory, and the fault part was confirmed. Finaly, the system design was improved and verified in the outfield experiments. The system performance was improved well and truly.
