An instrument combining a pulsed laser transmitter and optical receiver (usually a telescope) with an electronic signal processing unit used for the detection and ranging of various distant targets in the atmosphere, analogous to the principles of operation of microwave radar. 6, record 3, English, - lidar
Record number: 3, Textual support number: 1 CONT
The lidar technique operates on the same principle as radar; in fact, it is sometimes called laser radar. The principal difference between lidar and radar is the wavelength of the radiation used. Radar uses wavelengths in the radio band whereas lidar uses light, that is usually generated by lasers in modern lidar systems. 7, record 3, English, - lidar
Record number: 3, Textual support number: 2 CONT
There are three basic generic types of lidar : range finders, DIAL, and Doppler lidars. Rande finder lidars are the simplest lidars. They are used to measure the distance from the lidar instrument to a solid or hard target Differential Absorption Lidar(DIAL) is used to measure chemical concentrations(such as ozone, water vapor, pollutants) in the atmosphere. Doppler lidar is used to measure the velocity of a target High-resolution DEMs with vertical accuracy as good as 10 cm can be created with Lidar. Lidar is also better able to map bare earth elevations in forested or vegetated areas than other methods because only a single laser pulse needs to be able to reach between trees and the ground. 8, record 3, English, - lidar

From 1954-56 Greenaway served with the USAF Strategic Air Command on many arctic Flights aboard B47 and B52 aircraft.

RTW [residual transport wander] is the difference between Earth convergency(EC) and map convergency(MC), however it is expressed as a rate since the error depends also upon the vehicle velocity. Therefore the average RTW rate is a function of earth convergency, map convergency and elapsed time. 2, record 5, English, - Earth%20convergency

Phase space is composed of as many dimensions(or variables) as the scientist needs to describe a system's movement. With a mechanical system, scientists usually map the system's phase space in terms of position and velocity. In an ecological system, the phase space might be mapped as the population size of different species. 2, record 6, English, - phase%20space
