Radar target simulation device and method

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

• storing, via a memory device, the at least one radar scenario with respect to the device under test, and providing the at least one radar scenario to a radar simulation device;
• receiving a first number of radar signals from the device under test;
• simulating the at least one radar scenario by manipulating the first number of radar signals according to the radar scenario and generating a second number of manipulated radar signals;
• superposing the second number of manipulated radar signals with noise and/or fading;
• and
• transmitting, via at least two antennas, the second number of manipulated radar signals to the device under test;
• and
• wherein the memory device contains storage contents comprising storage cells, wherein each storage cell corresponds to the respective antenna of the at least two antennas.
