Automotive forward looking sensor test station
First Claim
1. A test station for testing a radar system, the test station comprising:
- a test chamber having a first end at which the radar system is disposed and a second end; and
a transmit/receive test (TRT) system disposed at the second end of the test chamber and operative to receive an RF signal transmitted by the radar system, process the received signal to simulate a predetermined scene by modeling a predetermined object within the scene based on at least one known parameter of a radar return associated with said predetermined object and transmit the processed signal toward the radar system.

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.

13. A method for testing the performance of a radar system, comprising the steps of:
-
providing a test chamber having a first end at which the radar system is disposed and a second end; providing a test antenna at the second end of the test chamber; receiving at the test antenna array an RF signal transmitted by the radar system through the test chamber; processing the received signal with a transmit/receive (TR) processor in order to simulate a predetermined scene in the field of view of the radar system; transmitting the processed signal through the test chamber to the radar system; and providing control signals to the radar system, said control signals being indicative of movement of the radar system relative to the predetermined scene. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
