A STUDY FOR A VELOCITY MEASURING SYSTEM USING DOPPLER TECHNIQUES
Abstract
An evaluation of a velocity measuring system using doppler radio techniques was completed. An estimate is given of the effects of atmospheric conditions on propagation of electromagnetic waves, track geometry and construction, reflection characteristics of the ground, track and objects in the vicinity, and track operating techniques. The results indicate that the system described is capable of measuring the velocity profile of the trajectory to an accuracy greater than 1 part in 100,000 being limited only by errors introduced by multipath transmission effects and readout frequency characteristics. Methods are given whereby these errors may be reduced. (Author)
