Abstract :
The design, fabrication, and test results obtained for an electronically scanned Wullenweber array are described. The array scanned rapidly in the azimuth plane and received signals over an 8-12 GHz frequency band independent of their frequency or signal characteristics. A minimum sidelobe level of 20 dB was desired. The heart of the system was the traveling-wave tube phase shifter which provided variable true time delay over the band.
