Abstract
A test station for testing the performance of an automotive Forward Looking Sensor (FLS) in detecting one or more targets in a predetermined scene within the field of view of the FLS. The test station includes a chamber having a first end at which the FLS is disposed and a second end at which a Transmit/Receive Test (TRT) system is disposed. The TRT system includes an antenna array responsive to an RF signal transmitted by the FLS and a Transmit/Receive (TR) processor for processing the received signal in order to simulate the predetermined scene and for transmitting the processed signal back to the FLS. The TR processor includes at least one Transmit/Receive Radio Frequency (TR RF) processor module for processing the received RF signal by selectively shifting the frequency and/or adjusting the amplitude of the signal.
