摘要： Disclosed is A wide FoV radar module for three-dimensional detection according to an embodiment of the present invention. According to the present invention, at least one of the plurality of transmission channel units includes a 1-1st transmission channel antenna arranged in the first direction, thereby being responsible for detecting the short/mid/long distance horizontal directions and the detection of the mid/long distance elevation angle directions, By including a 1-2nd transmission channel antenna arranged in a second direction different from the first direction, it is responsible for detection of the short-distance horizontal direction and detection of the short-distance elevation angle direction, and detects the horizontal direction compared to the prior art through a single radar module. In addition to performance, the detection performance in the elevation angle direction is improved, which has the effect of minimizing the number of mounting units.
