RADC-TR-66-15, FINAL REPORT: COMPACT ANTENNA RANGE TECHNIQUES (APR-1966) (484511]

RADC-TR-66-15, FINAL REPORT: COMPACT ANTENNA RANGE TECHNIQUES (APR-1966) (484511]., Techniques for making pattern and gain measurements on full-sized microwave radar antennas on indoor compact antenna ranges are described. A reflector and special feed system near the test antenna is used to produce incident plane waves, and far-zone results are obtained. Three basic configurations of compact ranges are discussed; they are a pointsource range, a line-source range, and a two-dimensional range. Pattern and gain measurements of a 30-inch parabolic test antenna were made on the point-source and line-source ranges, and the results were compared with measurements made on a conventional outdoor range. Special studies of stray radiation were made on the two-dimensional range.
