Gasgoo Awards 2023 applicant: 77GHz Automotive Corner Radar SR439 for Integrated Driving and Parking from Jiaxing Joospeed Electronic Technology Co., Ltd

Product: 77GHz Automotive Corner Radar SR439 for Integrated Driving and Parking 

Description

SR439 is an integrated-driving-and-parking millimeter-wave Radar developed by Joospeed Electronics. It can fully meet the complexity requirements of multiple application scenarios and solve various challenges in complex scenes through the fusion of 4D point cloud, Freespace, and deep learning object recognition. The SR439 radar has an azimuth detection range of ±75° and an elevation detection range of ±15°. It features both a conventional corner radar mode for driving and a 4D point cloud AVP (Automated Valet Parking) mode for parking. In driving mode, it functions as a traditional corner radar with a detection range exceeding 120 meters. In parking mode, it serves as a near-field 4D imaging radar with a detection distance accuracy of 2cm. It can be used for Level 4 autonomous parking and searching for parking spaces.

Unique advantages

1) Integrated driving and parking, combining multiple functions to reduce costs effectively. 2) Key chips are domestically produced, ensuring a secure supply chain. 3) Innovative real-time super-resolution angle measurement algorithm that breaks through the limitation of the physical aperture of a single-chip antenna, significantly improving angle measurement resolution. 4) In phased array radar mode, it adopts an innovative Bounding-Box Fitting + Tracking algorithm, enabling more accurate multi-target trajectory tracking. 5) Can provide customers with solutions for SLAM (Simultaneous Localization and Mapping), local positioning, and other upper-layer applications.

Application

1) Driving Scenarios: Blind Spot Detection (BSD), Lane Change Assistance (LCA), Door Opening Warning (DOW), Automatic Emergency Steering (AES), Traffic Jam Assistance (TJA), Rear Collision Warning (RCW), Forward Cross Traffic Alert (FCTA), Rear Cross Traffic Alert (RCTA). 2) Parking Scenarios: Automatic Parking Assistance (APA), Autonomous Valet Parking (AVP).

Prospect

SR439 radar has been deeply adapted to multiple mass production projects. With the large-scale production of the "integrated driving and parking" solution, the combination of sensors for intelligent driving and parking will undergo profound changes. Millimeter-wave radar and other sensors will experience a new upgrade, and the deep integration of multiple millimeter-wave radars and domain controllers will officially begin. SR439 is optimized and designed comprehensively for the integrated driving and parking application scenario in terms of hardware, software, algorithms, etc. It is an excellent performing millimeter-wave radar product with clear positioning, which will lead the competition in the integrated driving and parking perception market and achieve stable volume production.
