Abstract
A sidelobe blanking method is used with a radar system with a linear transmit array along a first axis and a linear receive array along a second axis perpendicular to the first axis. The method transmits a transmit guard signal using a transmit guard antenna with a wide beamwidth in both axes, determines a first guard signal strength of a signal captured by the receive array at a first receive angle, transmits a radar signal using the transmit array at a transmit angle, determines a second guard signal strength of a signal captured by a receive guard antenna with a wide beamwidth in both axes, receives a radar return signal using the receive array at the receive angle, and blanks the radar return signal when its signal strength is less than either the first guard signal strength or the second guard signal strength.
