A Novel Visibility Function Calibration Method Based on Multiple Point Sources for Passive Millimeter Wave Imaging: IEEE ICMMT 2024

Le résumé fourni par la source

Researchers and technicians extensively applied the synthetic aperture interferometric radiometer imaging (SAIR) to earth observation and radio astronomy. In recent past, the SAIR technique has been proved to be employed in passive millimeter wave (PMMW) security screening, and the phase errors calibration of visibility samples is a key step in the imaging process. To overcome the high complexity of traditional calibration methods, a novel calibration approach, which makes use of multiple point sources at different locations, is proposed to tackle this problem in this paper. The imaging results show the proposed method is sufficiently accurate to satisfy for the SAIR requirements.
