Two-element interferometer for accurate position determinations at 960 Mc

A 960-Mc two-element interferometer using the twin 90-foot steerable paraboloids of the California Institute of Technology Radio Observatory is described. The response of the associated receiving equipment as it applies to interferometric position measurements is analyzed in some detail, and an advantage of not rejecting the image response of the receiver is mentioned. Finally, a brief account is given of the various ways the interferometer may be used to measure right ascensions and declinations with both an east-west and a north-south baseline.
