MILLSTONE HILL RADAR STATION RESULTS OF LONGBASELINE RADAR INTERFEROMETER STUDIES,
Abstract
The Millstone-Lexington interferometer is a radar interferometer consisting of the Millstone radar transmitter, antenna, and receiver plus an auxiliary receiver station at Lexington, 13.7 nautical miles away. The final IF output of the Millstone receiver and a phase reference for the receiver's local-oscillator frequencies are transmitted to Lexington via a combination of a UHF and a microwave link. The rate of change in the phase of the signal received at Lexington with a 28-foot dish is compared with that received at Millstone to determine the angular velocity of a target. The over-all performance of the interferometer has been ascertained by a number of actual target observations. The observed phase as a function of time is compared point by point with a parabola of least-meansquare fit. The difference between these curves typically shows a random component of 15 degrees rms.
