Abstract :
Two pattern synthesis procedures have been developed for a traveling-wave linear array, fed at its center, with half the array forward-firing, the other half backward-firing, and the total array required to produce a squinted main beam and controlled sidelobes. The procedure is illustrated by the case of a 36-element slot array, designed to create a sum pattern with a -30-dB sidelobe level and the main beam tilted 2.25° off broadside. Center-fed traveling-wave arrays offer the potential of increased bandwidth and a frequency-independent squint angle
