Abstract:
A method of aligning a bore site angle of an automotive radar antenna with respect to a mechanical reference line from a vehicle, the method comprising the steps of:positioning a first receiving antenna and a second receiving antenna along a first line, said first and second receiving antennas having centerlines approximately perpendicular to said first line, said first and second receiving antennas being separated along said first line, said first line having a midpoint between said first and second receiving antennas; positioning said first and second receiving antennas with respect to said radar antenna such that a centerline of said radar antenna approximately intersects said midpoint of said first line, wherein said centerline of said radar antenna is approximately perpendicular to said first line and approximately parallel to said mechanical reference line; transmitting a radar signal from said radar antenna; measuring a first signal received by said first receiving antenna in response to said radar signal; measuring a second signal received by said second receiving antenna in response to said radar signal; generating a third signal indicating a difference between said first and second signals; and adjusting said radar antenna until said third signal is a minimum.
