着重对影响测向精度的因素进行误差分析，提出了一种改进的快速测向校正新方法。在分析影响多通道数字干涉仪测向通道相位测量精度的因素的同时，对自检源进行了改进设计，提高了系统校正的速度。该方法既降低了自检源的设计要求，也降低了微波通道相位一致性的设计要求。试验结果表明通过定时或实时测向通道校正，大大地缩短了系统校正时间，测向精度得到了明显提高。

The error factors which influence DF accuracy of multi-channel digital interferometer is ana- lyzed in detail and a novel method of improved rapid DF correction is proposed. Meanwhile, BIT source is redesigned and system correction speed is enhanced. This method decreases design requestsof BIT source and microwave channel phase coherence. Trial results show through timing and real- time DF channel correction, system correction time is shortened greatly and DF accuracy is improved obviously.
