High-resolution millimetre wave images of contiguous targets often suffer from the influence of sidelobe artefacts, partial correlation between targets and so on. Owing to the characteristics of near-field synthetic aperture imaging radiometers [such as the changing point spread function (PSF) and slender sideline], the existing CLEAN algorithms are unsuitable for near-field synthetic aperture imaging...
In order to overcome the disadvantage of large data amount and receiver number in near-field passive millimeter-wave synthetic aperture imaging radiometer (PMSAIR), an imaging algorithm based on Compressive Sensing (CS) theory is proposed in this paper. Due to the fact that the brightness temperature distributions of the observed target have a sparse representation in some proper transform domain...
