The joint research team led by Sangdong Kim and Bongseok Kim from the Automotive Technology Division of DGIST has developed a new radar signal-processing technology that enhances the resolution of existing low-resolution radars. This technology allows for precise object recognition using existing hardware specifications without the need for bandwidth expansion. The technology addresses the need for resolution-enhancement technologies in radar systems for automotive and aerospace applications, without increasing costs or system complexity.
The team discovered that additional information embedded in the envelope of radar signals could be utilized and developed a new algorithm that analyzes the contour features of received signals. This innovative technology improves target differentiation without requiring bandwidth expansion, achieving nearly double the resolution through signal processing on existing radar hardware. It also enables the precise identification of objects both inside and outside the vehicle. The team aims to further enhance this technology for practical applications in autonomous vehicles and industrial environments.
Dr. Bongseok Kim of DGIST expressed his satisfaction with the publication of their work in the IEEE Sensors Journal and highlighted the team’s commitment to continue developing the technology through further research. The research was supported by DGIST’s general project (D-PIC 4.0) and the National Research Foundation of Korea’s Basic Research Support Program.
