一种新的无线电高度表原位检测的高度模拟方法

摘要

In order to meet the requirements of the altimeter's in-situ testing, we investigated a new method to simulate the height. This method, based on ARM microprocessor , produced a variety of signals of height by a digital-analog conversion circuit. It was also very simple, fast and high reliability. Experimental results indicated that this method was with high accuracy and had a high practical value and e-conomic benefits.%针对目前对高度表进行原位检测的需求,设计了一种新的高度模拟方法；该方法的实现以ARM为核心,通过高度模拟电路产生各种需要的高度电压信号,从而达到高度模拟的目的,并且无需对机载高度表进行拆装,操作简单、快捷、可靠性较高;实验结果表明,这种方法的高度模拟精度较高,具有一定的实用价值和经济效益.
