Altimeter explanation: instruments using air pressure, radar, etc. Height measurement, often used in aviation and mountaineering. Also called altimeter.

Altimeter sentence: 1, the altimeter stays in that position for most of the 14 hour journey.

2. The wind passing through the ocean directly affects the height of waves and the data measured by altimeters and periodic monitors used by orbiting satellites.

3. The new detector is built with improved electronic equipment and battery pack, and a new radar altimeter is added, which is a device to measure the thickness of polar ice by emitting microwaves.

4. The working principle of the laser altimeter (LOLA) on the lunar probe is to emit a laser pulse, which is divided into five beams through the optical lens, and will automatically reflect to the laser altimeter when it reaches the lunar surface.

5. Then the laser altimeter will calculate the transit time of the reflected pulse with reference to the speed of light, so as to get the distance from the spacecraft to the surface of the moon.

6. I looked at the altimeter on my wrist, and it has risen to 13500 feet, which means it's time to jump.

7. Altimeter is used to measure height.

8. Put your Nokia touch device on the altimeter and check whether your height is higher than the sea level, no matter where you are.

9. The calibration methods of sea surface height and backscattering coefficient in satellite altimeter calibration are introduced.

10. Based on the existing data and theoretical model, the calculation method of radar echo intensity is proposed, and the new altimeter system is simulated by computer.

1 1. As a pioneer, with the success of our R&D capability and production capacity, we are very proud to introduce our barometer, altimeter, weather station, clock, LED and handshake torch to you.

12. In order to achieve high spatial resolution of spaceborne laser altimeter, a ranging method combining pseudo-random code modulated fiber laser and single photon counting is proposed.

Fortunately, after adding an altimeter to the system, this difficulty can actually be completely alleviated.

14. The altimeter display step 1 m adopts the built-in GPS.

15. According to the theory of solar radiation transmission, the solar radiation of the spaceborne near-infrared laser altimeter prototype in different postures is analyzed.

16, GPS speedometer, altimeter, compass and gravimeter.

17. A system simulation method of radar altimeter is introduced.

18. Satellite altimetry is a comprehensive subject developed with satellite remote sensing measurement technology. It uses the radar altimeter loaded on the satellite to measure the average height, effective wave height and backscattering coefficient from the satellite to the sea surface.

19. Three different combination schemes of radar altimeter are analyzed.

20. I adjusted my altimeter until the reading on the head-up display showed zero, so that all the readings I saw during the whole performance were relative to the ground.

2 1. The basic principle of satellite navigation with inclined antenna radar altimeter and radar altimeter combined with other sensors is introduced.

22. Since 1999, we have successfully developed a variety of micro air vehicles, including micro airborne electronic equipment, such as autopilot, altimeter, airspeed indicator, micro communication, micro camera and so on.

23. In order to provide technical guidance for satellite ocean radar altimeter, an airborne ocean radar altimeter is developed, and its core work is adaptive control system.

24, beware of clock and altimeter damage.

25. The researchers compared the ice thickness and ice extent estimated by 1970 during an aerial observation with the ice thickness and ice extent measured by the airborne laser altimeter in 2007 and 2008, and obtained the above figures.

26. Deep-sea sonar altimeter is an echo sounding device equipped with deep-sea detection equipment.

27. With the wide application of altimeter data and the development of numerical model of vortex resolution, the study of mesoscale vortex in the South China Sea is becoming more and more active.

28. In this paper, the characteristics and laws of the earth echo of LFMICW radar altimeter are deeply studied.
