A team of researchers, spearheaded by Sangdong Kim and Bongseok Kim from the Automotive Technology Division of DGIST, has introduced a groundbreaking radar signal-processing technology that significantly enhances the resolution of standard low-resolution radar systems. This advancement allows for more accurate object detection and differentiation while utilizing the existing hardware capabilities without necessitating any increase in bandwidth.
In the fields of automotive and aerospace technology, radar systems increasingly rely on resolution-enhancement techniques to boost the accuracy of object recognition. Traditionally, achieving greater resolution requires either widening the bandwidth or implementing complex ultra-high-resolution algorithms, both of which can lead to elevated costs and increased system intricacies.
The research team uncovered that additional data contained within the envelope of radar signals could be leveraged to improve resolution without the need for bandwidth expansion. They successfully developed an innovative algorithm designed to analyze the contour features of these received radar signals. This new approach not only allows for the enhancement of target differentiation but also nearly doubles the resolution, all accomplished through processing on existing radar hardware. The technology also facilitates precise identification of objects located both inside and outside vehicles.
Dr. Bongseok Kim expressed his satisfaction with the project’s recognition, stating, “I am thrilled that our work has been published in the IEEE Sensors Journal. Our team is committed to further refining this technology to support its application in autonomous vehicles and various industrial settings.”
This significant research endeavor was made possible through the support of DGIST’s overarching project (D-PIC 4.0) alongside the Basic Research Support Program facilitated by the National Research Foundation of Korea. The findings, with Dr. Bongseok Kim as the lead author and Dr. Sangdong Kim as the corresponding author, were officially published in the IEEE Sensors Journal in December.
