ARRAY BEAM SWITCHING STUDY.
Abstract
The study examines techniques of beam switching to establish their suitability for production of large, low cost, wideband systems. Limits on the study are from UHF thru X-band with 400- to 1000-MHz bandwidths and 1-KW to 1-MW peak power. Chief conclusions of the study are: (1) Switched beam concepts using a subarray approach offer advantages in terms of efficiency and economy for systems requiring intermediate sidelobe levels (20 to 25 db), (2) A wideband six-port design method is available for UHF through S-band, (3) Testing of available array-oriented components showed the parameters most necessary to characterize them, and indicate automated measurement and data reduction techniques are desirable, (4) Pulse distortion effects of array components (using both theoretical and experimental data) can be determined using digital computer techniques; this method is useful when paralleling similar threads, and (5) Combinations of switch and beamforming matrices have been found for high and low power applications. They can be made in medium power levels (10- to 30-KW peak) in stripline, and, for receiving applications, can be made in hybrid integrated circuit form. (Author)
