Abstract : The report presents results of tests in 1969 aboard BUNKER HILL and at Border Field to establish the bearing accuracy of the phase comparison technique against known emitters at known locations. Plotted data enable the reader to view the results from particular test locations and receiver sites, and to study the azimuth, range, and accuracy obtained. Sources of error are analyzed. It is concluded that the phase comparison direction finder, using sin theta and cos theta parameters to determine bearing, is applicable to shipboard direction finding where site conditions and operational accuracy requirements are not overly severe.
