摘要
给出了比幅测高的基本原理,分析了影响比幅测高精度的主要原因,着重分析了各路增益不平衡对测高精度的影响。根据实际工作中的具体情况,提出一种简单易行的自动补偿方法,以改善各路增益的一致性,提高测高精度。
The paper presents the basic principle of the amplitude-comparison height measurement and analyzes the main cause influencing the height-measurement accuracy.mainly analyzing the influence of the unbalance of channel gain. Based on the practical operating situation of e-quipment.we provides a kind of simple and easy method of self-compensation so as to improve the consistency of channel gain and thus to enhance the height measurement accuracy.
