Environment parameters FVR30 radar related environment parameters are as below:

1) Storage temperature: -40 ~ 105 2) Operating temperature: -40 ~ 85 3) Function limited operating temperature: 85 ~ 95 Calibration method FVR30 radar supports static calibration, dynamic calibration and self-calibration of azimuth installation angle. 1) Static calibration is carried out by special calibration equipment when the vehicle is off the assembly line. 2) Dynamic calibration is generally used after the vehicle is off the line, or 4S after-sales maintenance, through a specific calibration road, after driving some distance, automatically complete the calculation of the calibration angle. 3) Self-calibration is that the vehicle automatically identifies the external environment during normal driving, and automatically self-calibrates when the calibration conditions are met. Freetech Intelligent Systems Co., Ltd. Front View Millimeter Wave Radar FVR30 Product Specification NoRPS-003 VersionV2.4 Released date 2023-8-2 Page 9 / 12 Installation Instruction FVR30 radar is fixed to the body by a mounting bracket, as shown in the figure below:

The safe distance of the radar mount from the radar edge is 5mm. Figure 7: Way to install A "second surface" (usually the car logo, bumper, and specially designed radar radome) needs to exist between the radar sensor and the exterior of the car to avoid the sensor from stone impact and ultraviolet radiation. The radar cannot be left open without a second surface. The position and orientation of the radar relative to the second surface cannot usually be specified in detail, but can be evaluated separately depending on the application. The optimal system performance of the second surface depends on the following factors:

Thickness Material Form Distance Uniformity Degree of inclination and curvature Paint The customer needs to provide enough second surface samples. For cases where the second surface is a bumper, the customer needs to provide various bumper configurations, covered with different paints and varnishes. Experience shows that white and silver paints have high amount of metal particles and therefore have a greater impact on radar signals. Snow on the second surface causes degradation of the quality of the radar signals. In order to reduce accumulated snow, the second surface cannot be designed with horizontal gaps and grooves.
