Abstract

The invention relates to the technical field of automotive radars, in particular to a vehicle-mounted radar calibration device and a calibration method thereof. The calibration device comprises a radar mounted on a to-be-calibrated vehicle and a calibration assembly disposed behind a vehicle-mounted radar. The calibration assembly includes a horn antenna and a copper-shaft cable; the horn antennais arranged right behind the vehicle-mounted radar; the copper-shaft cable connected with the horn antenna is used for transmitting a millimeter wave and reflecting the millimeter wave to the vehicle-mounted radar; and the vehicle-mounted radar sends calibration assembling information obtained by detection to calibration software for correction. According to the invention, since the copper shaft cable is used for transmitting the millimeter wave and can be wound, the occupied field is smaller than that in the target simulator scheme and the corner reflector scheme. After the horn antenna is connected with the copper shaft cable, the calibration device is arranged at a position being close to the radar, so that most of signal interferences can be avoided and the calibration accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of automotive radar, in particular to a vehicle-mounted radar calibration device and a calibration method thereof. Background technique [0002] Because there is a visual blind spot in the rearview mirror of the car, the vehicle in the blind spot cannot be seen before changing lanes. If there is an overtaking vehicle in the blind spot, a collision accident will occur when changing lanes at this time. [0003] In order to solve the blind spot problem of the rearview mirror, people install blind spot radars on the left and right sides of the rear bumper of the car. When a vehicle is detected in the blind spot approaching, the indicator light flashes. At this time, although the driver cannot see the vehicle in the blind spot , but you can also know that there is a vehicle coming from behind through the indicator light, and there is a risk of collision when changing lanes, so as to avoid the occurrence of collis...
