Abstract : A pulse radar system operating at 36.8 MHz was placed in operation in 1967 at the University of New Hampshire, Durham, N. H. for the measurement of wind speeds at altitudes between 80 and 120 km through observations of the drift in the ionization trails of meteors. Subsequent modifications were made to provide an offset Doppler channel for low velocity sensing. An echo direction finding capability of plus or minus 1 degree in elevation and azimuth was achieved through the development of a time-shared phase sequence interferometer. System calibration was carried out with the aid of a ground controlled beacon transmitter in satellite OV1-17. (Author)
