초록 ▼

Two receive antennas integrated with power detectors are used to align the thrust vector of a vehicle to the boresite of an automotive radar antenna mounted upon the vehicle. In the system, a signal is transmitted from the radar antenna to the Radar Test System (RTS) positioned as an amplitude only interferometer for testing the radar. Signals received by the RTS antennas are provided to amplitude detectors for generation of amplitude plots of a difference signal, or alternative signal, for display. The boresite angle of the radar antenna is then adjusted until the amplitude of the difference signal, or alternative signal, reaches a minimum to align the radar antenna boresite with the vehicle thrust vector. Additional pairs of receive antennas and detectors may be used to provide boresite alignment both in azimuth and elevation.

대표청구항 ▼

1. 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.
