DOI: 10.1109/tim.2019.2954758
Abstract: Although significant progress has been achieved in microwave imaging, high/super-resolution imaging remains a long-sought-after goal. A subwavelength imaging based on temporal–spatial random illuminations is experimentally investigated. Experiments are conducted using a single-frequency array aperture with… read more here.
