Initial evaluation work on operation of the Madre radar against aircraft targets over the North Atlantic Ocean was reported in Parts 1 and 2 of this series. This report continues with further observations of targets of opportunity within the slant range block 1350 to 1800 nautical miles. Propagation conditions were fair to good. The Madre radar was operated on 16.16 Mc with 100 kw average power applied to the broadside array sighting on an azimuth of 71 degrees. Ten apparent time vs range plots of aircraft are analyzed against position data obtained from the FAA and the Canadian Department of Transport, and again the Madre data are identified with specific flights but often without discrimination between several flights. Finer azimuth discrimination could be installed in the present equipment (beam splitting techniques) but is not believed necessary at present in the evaluation of the radar capabilities.
