一、前言在实际工作中,有时二次雷达显示出来的高度与飞机本身的高度存在较大的误差,这种误差有时容易引起管制员做出一些不必要的反应,因此,有必要对高度显示误差原因进行一些分析。二次雷达显示出来的高度是由雷达向飞机发送高度询问,飞机接收到后再根据气压高度计测出高度自动应答的结果。因此,一般认为飞机的高度显示误差是飞机的原因。事实上,这种误差与雷达设备的高度推算方法也有一定的关系,本文将对高度显示误差的原因作一些分析,进而为空管各部门制定特殊情况处置方案提供一些参考。二、原因分析一般而言,飞机的高度误差有三个原因:一是飞机气压高度计的误差;二是飞机的最小高度量化间
I. Preface In actual work, sometimes there is a big error between the altitude displayed by the secondary radar and the height of the aircraft itself. Such error may sometimes cause the controller to make some unnecessary reactions. Therefore, it is necessary to display the altitude Some reasons for error analysis. Secondary radar shows the height of the radar to the aircraft to send a high degree of inquiry, the aircraft received after the height of the air pressure measured height automatic response results. Therefore, it is generally believed that the height of the aircraft shows the error is the reason the aircraft. In fact, this kind of error is also related to the height estimation method of radar equipment. This article will make some analysis on the causes of height display error, and then provide some references for ATC departments to make special situation disposal solutions. Second, the reasons for the analysis In general, the aircraft height error for three reasons: First, the error of the aircraft barometric altimeter; Second, the minimum height of the aircraft Quantize Room
