ANTENNA FOR USE WITH A RANGE-GATED, PULSE DOPPLER RADAR SYSTEM

摘要

Abstract of the DisclosureAn antenna array radiation pattern switching system suitable for usein range-gated, pulse doppler, radar systems. The antenna array includes firstand second antennas, one of which is fed through a fixed phase-shift networkwhile the other is fed through a phase-shift network with double the phaseshift of the fixed phase shift network that can selectively be switched in andout of the feed circuit.
