FIXED AND MULTIPLE FREQUENCY ANGLE MEASUREMENTS WITH 35-GHZ MICROWAVES.
Abstract
The report covers the results of tests conducted at Fort Belvoir, Virginia, from 14 September through 28 October 1965. These limited tests were performed to determine the feasibility of 35-GHz angle measurements at a fixed frequency instead of multiple frequencies. Analysis of the data collected at Fort Belvoir and from previous tests at San Diego, California, and Boulder, Colorado, indicates that fixed frequency angle measurements are feasible if enough angles are turned, the readings are taken over a period of hours, and all inconsistent results are rejected. In general, the fixed frequency angles are more inconsistent and unreliable than the multiple frequency angles, the variations from the true angle are approximately twice those of the multiple frequency angles, and the time necessary for one fixed frequency measurement is approximately twice that of multiple frequencies. Included is an 8-hour boresight stability run. This run did not show the characteristic increase in angle of arrival excursion during the afternoon hours as was seen during the San Diego and Boulder tests. (Author)
