Experimental Millimeter-Wave Radar Image Analysis for Ice Detection in Low-Temperature Environments

This study proposes an experiment utilizing millimeter-wave (MMW) radar technology with FMCW modulation, featuring a center frequency of 94 GHz and a bandwidth of 1 GHz, to image targets in low-temperature environments. Imaging experiments were conducted on ice cubes of varying dimensions from different viewpoints. The experimental results show that the MMW radar successfully obtained the contour images of ice cubes in different forms, and the minimum ice cube length was 7 cm. Radar waves can penetrate the ice layer and reflect the contours of the ice cubes, thereby achieving high-resolution imaging. This research verifies the effectiveness of radar imaging in low-temperature environments and provides new technical ideas for fields such as ice and snow research and non-destructive testing of materials.
