Abstract:

Field tests were made to evaluate the accuracyresolution relationship of the NAVAID systems LoranOmega for measuring the vertical profile of the wind. Specifically, these tests involve a series of flight comparisons between the ANFPS-16 radar and the Omega and Loran equipments. These comparisons were performed using balloon-borne radiosondes with the receiving and processing equipment located on the ground. The specific Air Force requirements are for an accuracy of 3 knots with a 2000 ft sensing interval and a fall rate of 1000 ftmin or greater. The Loran equipments were found to be capable of a 1.4 knot accuracy for these conditions, while the Omega equipments provided an accuracy of 4.3 knots. Author
