Abstract
A Forward Looking Sensor (FLS) alignment system includes a transmit antenna adapted to provide multiple beams, a receive antenna adapted to provide multiple beams, a transmitter coupled to said transmit antenna and adapted to radiate an electromagnetic signal through selected ones of the multiple antenna beams of said transmit antenna and a receiver coupled to said receive antenna and adapted to receive through selected ones of the multiple antenna beams of predetermined antenna beams of a receive antenna having multiple antenna beams reflections from the radiated electromagnetic signal and processing the received electromagnetic signal reflections to generate an alignment offset signal.
