Antenna Ratio Calibration for the Afcrl Meteor Radar Using OV1-17

摘要

Experiments using a beacon transmitter at 36.8 MHz, including in the scientific payload of satellite OV1-17 to test and calibrate direction-finding techniques associated with the University of New Hampshire/AFCRL Meteor Trails Radar are reported. Comparison is made between a passive system which seeks to determine source elevation by examination of the ratio of signals received on two dispoles, lambda/2 and lambda/4 above a ground screen and a phase sequence interferometer in which the pattern nulls are actively scanned in azimuth and elevation.
