Cosmic rays and Geigertubes have been combined in a new altimeter to tell the pilots what their altitudes are. 宇宙线兴盖氏管已过连接成为一种新的高度计用来告诉飞行员他们的高度是多少。
The simulation result shows that the approach can effectively limit high frequency random noise of altimeter and compensate delay error. 仿真结果表明该方法可以有效地抑制高度表的高频随机噪声和补偿其延迟误差。
This paper introduces briefly the principle of radar altimeter and its development around the world. It also introduces its application on ocean, ice or glacier and inland water. 摘要21世纪初,星载雷达高度计已经进入全球业务化阶段,我国在这方面还是相对落后,鉴此本文介绍了星载雷达高度计的技术原理和发展历程,并较为全面的介绍了高度计在海洋、川研究和内陆湖泊、流等水文方面的应用。
altimeter
[ noun ] an instrument that measures the height above ground; used in navigation <noun.artifact>
Altimeter \Al*tim"e*ter\, n. [LL. altimeter; altus high + metrum, Gr. ?, measure: cf. F. altim[`e]tre.] An instrument for taking altitudes, as a quadrant, sextant, etc. --Knight.
Navcom Defense Electronics Inc. received a $67.1 million Air Force contract for a radar altimeter system.
It incorporates a mechanical altimeter and a barometric scale, as well as an oil-mounted compass that is also water resistant.
Even now, Carpenter says: 'We were flying the aeroplane with a compass and a tacometer and an altimeter, all of which said everything was normal.'
