The radar target simulation device 110 is configured to receive a detection signal emitted by the millimeter wave radar 200 to be detected through the transceiver antenna 130, generate a target echo signal according to the detection signal and a set simulation target parameter, and radiate the target echo signal into the microwave camera bellows 120 through the transceiver antenna 130, so that the transceiver antenna 130 can be disposed inside the microwave camera bellows 120, for example, on an inner side wall of the microwave camera bellows, and at this time, the rack 140 and the transceiver antenna 130 can be disposed opposite to each other to ensure effective transmission of the echo signal therebetween.
