Harnessing Frequency Diversity for Improved Holographic Imaging Systems
Paper i proceeding, 2024
This study investigates the impact of varying the illuminating frequency spectrum over time in a 340 GHz FMCW radar system with a holographic setup. Experiments using a corner cube reflector explored the behavior of spatially varying frequency-dependent field patterns across bandwidths ranging from 326 to 356 GHz. Findings suggest that varying the illuminating frequency spectrum over time can capture more spatial information from the target than using the radar's entire bandwidth allowing for improved target discrimination and imaging capabilities in holographic radar systems.
