The invention discloses a novel automobile door opening grading early warning feedback system based on a millimeter wave radar. The early warning feedback system comprises an MCU, a radar, a pressuresensor and an alarm device, the pressure sensor is arranged on an automobile door, the MCU establishes communication with an ECU of an automobile, and after the automobile is started, the MCU operatesa monitoring system to be started. The detection system comprises the following operations: reading the speed of an automobile; judging whether the real-time automobile speed is lower than an automobile speed threshold value or not, and starting a pressure sensor when the real-time automobile speed is lower than the automobile speed threshold value; reading a pressure value of the pressure sensor; judging whether the real-time pressure value is lower than a pressure threshold value or not, and locking the vehicle door when the real-time pressure value is higher than the pressure threshold value; starting the radar on the same side of the locked vehicle door; reading radar information, and calculating relative position information between the workshop and the target object in the range bythe MCU based on the radar information; and by the MCU, executing a multi-stage early warning strategy based on the relative position information. The system is simple in structure and convenient to use.
