Design and implementation of a radar-camera integrated system based on dual RF chip cascade

Abstract： In the field of Intelligent Transportation Systems (ITS), radar-camera integrated systems offer advantages such as lower cost and enhanced data fusion compared to the combination of standalone radar and checkpoint cameras. This study utilizes RF chip cascade technology to enhance the performance of millimeter-wave radar and integrates a professional-grade security chip to design a radar-camera integrated system with long-distance detection capabilities. A multi-sensor fusion algorithm is employed, and the target detection algorithm, YOLOv8n, is improved by replacing the backbone feature extraction network and loss function. These improvements reduce the parameter count by 24% and the model size by 22%. Real-world traffic scenario tests validate the reliability of the system, achieving comprehensive monitoring of traffic intersection scenarios. The system demonstrates a maximum detection range of 350 meters and a detection accuracy exceeding 97%, meeting the design requirements for long-range traffic radar-camera integrated systems.
