摘要

We investigate the impact of placing a thin flat radome in front of an amplitude-only direction finding (AODF) antenna system. The considered system consists of two identical Ka-band, air-filled horn antennas squinted off boresight by 30degrees for direction finding (DF) error within ±0.82degrees/dB over a field-of-view (FoV) from -20degrees to +20degrees. Computational results with various radome materials, thicknesses, and placements indicate that it is possible to maintain excellent DF performance if radome is properly designed and located.
