Radar target simulation device and method

A radar simulation method for testing a device under test with respect to at least one radar scenario, the radar simulation method comprising:

• storing, via a memory, the at least one radar scenario with respect to the device under test, and providing the at least one radar scenario to a radar simulator;
• receiving, by the radar simulator, a first number of radar signals from the device under test, simulating the first number of radar signals based on the at least one radar scenario, and generating a resulting second number of manipulated radar signals;
• and
• transmitting the second number of manipulated radar signals to the device under test.

A system comprising:

• a device under test;
• and
• a radar simulation device comprising a memory, a radar simulator and at least two antennas, wherein the radar simulation device is configured for testing the device under test with respect to at least one radar scenario;
• and
• wherein the memory is configured to store the at least one radar scenario with respect to the device under test, and to provide the at least one radar scenario to the radar simulator, and
• wherein the radar simulator is configured to receive, via one or more of the at least two antennas, a first number of radar signals from the device under test, to simulate the at least one radar scenario by manipulating the first number of radar signals based on the at least one radar scenario and generating a resulting second number of manipulated radar signals, and to transmit, via the at least two antennas, the second number of manipulated radar signals to the device under test.

A training system for training an autonomous vehicle with the aid of at least one traffic scenario, the training system comprising:

• a memory;
• a radar simulator;
• at least two antennas;
• an optical simulator;
• and
• a display;
• and
• wherein the memory is configured to store the at least one traffic scenario and to provide the at least one traffic scenario to the radar simulator and to the optical simulator,
• wherein the radar simulator is configured to generate a radar representation of the at least one traffic scenario by receiving a first number of radar signals from at least one radar sensor of the autonomous vehicle via the at least two antennas, generating a second number of manipulated radar signals by simulating the at least one traffic scenario based on a manipulation of the first number of radar signals with respect to the at least one traffic scenario, and transmitting the second number of manipulated radar signals to the at least one radar sensor of the autonomous vehicle via the at least two antennas, and
• wherein the optical simulator is configured to generate an optical representation of the at least one traffic scenario based on the second number of manipulated radar signals, and
• wherein the display is configured to display the optical representation of the at least one traffic scenario.
