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.
Claims12
A Forward Looking Sensor (FLS) comprising:
- (a) a transmit circuit comprising a transmit antenna for transmitting an RF signal, said transmit antenna comprising a plurality of radiating elements generating a plurality of radiating beams spaced relative to one another by a predetermined amount and wherein at least a portion of each antenna beam overlaps at least one other antenna beam by a predetermined amount and wherein the plurality of radiating elements generating a plurality of radiating beams comprises at least one beam pointing in an upward direction;
- and
- (b) a receive circuit comprising a receive antenna for receiving an RF signal.
A method for aligning a Forward Looking Sensor (FLS) comprising the steps of:
