The vehicle mounted millimeter wave radar measurement system developed by Sunyield has been put into use, and many vehicle mounted radar tests including Nio Inc. have been completed. With the help of Sunyield test system, automobile manufacturers can test more scenes faster and earlier, accelerate the mass production process of vehicle mounted millimeter wave radar, and provide assistance for the early realization of fully automated driving.
Recently, with the gradual expansion of attempts to put autonomous passenger vehicles on the road, China’s penetration rate and commercialization of autonomous driving are accelerating. New air vents are forming, and the scale of autonomous driving production is constantly increasing. The commercial application of advanced autonomous driving is also gradually expanding in specific occasions such as trunk logistics, ports, and mines. Behind the flowering of autonomous driving, as an important component of the perception layer, the onboard millimeter wave radar has also moved from behind the scenes to under the spotlight, becoming a hot topic of concern.
Vehicle mounted millimeter wave radar is a detector that measures the distance, orientation, and velocity of targets by emitting electromagnetic waves and receiving their reflected echoes. At present, the onboard radar frequency bands of major countries are mainly concentrated in the three frequency bands of 24GHz, 60GHz, and 77GHz. Using this frequency band of electromagnetic waves can form narrower and more directional beams, improve the radar’s resolution of targets, and have strong ability to penetrate dust, smoke, and rain. The website of the Ministry of Industry and Information Technology has released the “Interim Regulations on Radio Management of Automotive Radar”, which specifies that the 76-79GHz frequency band is used for automotive radar. The main usage scenarios include adaptive cruise control, collision prevention, blind spot detection, lane change assistance, parking assistance, rear vehicle warning, pedestrian detection, etc.
SY-Radar Automotive Millimeter Wave Radar Testing System
The SY-Radar car mounted millimeter wave radar measurement system has a high testing frequency band and a small volume. It is mainly used for testing the relevant indicators of 60/77/79 GHz car mounted millimeter wave radar, and can achieve measurement and calibration of the target distance and target amplitude of the measured object radar; At the same time, the relative angle can be calculated based on the distance and position of the target, and the target angle can be measured and calibrated.
The vehicle mounted millimeter wave radar measurement system developed by Sunyield has been put into use, and has completed the test of several vehicle mounted radars, including Nio Inc.. With the help of Sunyield test system, automobile manufacturers can test more scenes faster and earlier, accelerate the mass production process of vehicle mounted millimeter wave radars, and provide assistance for the early realization of fully automated driving.
The SY-Radar on-board millimeter wave radar measurement system is equipped with a high-precision multi-axis turntable, including pitch/azimuth axis, automatic insertion and extraction, and clamping/releasing devices. The pitch axis can adjust the attitude of the radar during the test process. The azimuth axis can measure the horizontal azimuth of the radar. Through the azimuth axis, the pitch axis and the angular displacement axis, the Test effort of multiple spatial angles and multiple orientations can be achieved.
