Abstract

The present invention relates to an electromagnetic compatibility testing system and method for a radar sensor for an autonomous vehicle, wherein the radar simulator unit generates radar object information based on virtual driving information and virtual obstacle information received from a virtual driving simulator unit, generates a radar signal synchronized with a preset virtual driving scenario of the virtual driving simulator unit based on the radar object information generated by the radar simulator unit, and transmits the radar signal to a radar sensor mounted on an autonomous vehicle through a radar antenna unit, thereby performing an electromagnetic compatibility test of the radar sensor mounted on the autonomous vehicle while virtually simulating a situation in which the autonomous vehicle operates on an actual road inside an electromagnetic shielding chamber unit, the accuracy and reliability of the electromagnetic compatibility test are improved, the time and cost of the electromagnetic compatibility test are reduced, and the commercialization of the autonomous vehicle is promoted.
