1. A testing system of a radar sensor for an active environment sensing system, comprising:
a first electronic control unit;
a first receive antenna, connected to the first electronic control unit, for receiving a radar sensor signal;
a first transmit antenna, connected to the first electronic control unit, for emitting a first radar echo generated by the first electronic control unit;
a second electronic control unit;
a second receive antenna, connected to the second electronic control unit, for receiving a radar sensor signal;
a second transmit antenna, connected to the second electronic control unit, for emitting a second radar echo generated by the second electronic control unit; and
a switching apparatus configured to switch the testing system between a first configuration corresponding to a first test and a second configuration corresponding to a second test;
wherein, as part of the first test, the first transmit antenna or the second transmit antenna is configured to simulate a plurality of targets,
wherein, as part of the second test, the first and second transmit antennas are configured to simulate first and second targets, respectively, and
wherein the switching apparatus comprises:
a first switch connected to a second output and configured to connect and disconnect the second transmit antenna from the second output;
a second switch connected to a second input and configured to connect and disconnect the second receive antenna from the second input;
a third switch connected to a first output and configured to connect the first output to the first transmit antenna; and
a fourth switch connected to a first input and configured to connect the first input to the first receive antenna.
