Abstract : The report itemizes the advantages and unique characteristics of the Crossed Beam two-dimensional Radar Scanning (CBRS) techniques along with the supposed disadvantage of low aperture efficiency. More than 50 illustrations are used to carefully exhibit design techniques, specific test methods and results, including 16 mm and 8 mm action film clips, which exhibit system and antenna performance. Major emphasis is given the 49 element, series-parallel ferrite, Ku-Band, electronic scanning (30 degrees continuous scan in 1200 us) antenna. Performance of both the 25 frame/second Electromechanical (vibrating ridge) and the Electronic Antenna is demonstrated through comparison of optical and microwave images, when using either antenna to transmit or receive. The antennas are demonstrated using a radar system. Range capability of less than 10 feet and more than 2 miles is demonstrated.
