Classification: CPC G | IPC G

Claim 0:
1. A test system for testing a radar sensor, the test system comprising:
a test chamber for encompassing a radar sensor to be tested, wherein a test location is provided within the test chamber on which the radar sensor to be tested is placed for testing;
at least one antenna unit;
at least one first radar target simulator connected to the antenna unit;
at least one antenna array different from the antenna unit; and
at least one second radar target simulator connected to the antenna array such that two different radar target simulators as well as two different antenna systems are provided in a single test system,
wherein the at least one first radar target simulator is different than the at least one second radar target simulator,
wherein the test system has a first operation mode that corresponds to an angular calibration of the radar sensor to be tested which uses a plane wave that incidents on the radar sensor to be tested at the test location,
wherein, in the first operation mode, the test system is configured such that only the antenna unit is operated, and in a second operation mode, the test system is configured such that only the antenna array is used for multi-target tests,
wherein the test system has an outer housing that limits the test chamber outwardly, and wherein the antenna unit as well as the antenna array are provided in the same test chamber.
