a The working system for human security inspection. b The block diagram of the transceiver system. c A resolution target and corresponding full-sampled imaging results. The groups 4, 5, 6, and 7 correspond to the resolutions of 4 mm, 5 mm, 6 mm, and 7 mm. d The untrained reconstructions of random and statistically optimized sparse arrays. The resolutions of these arrays are 10% random >7 mm, 10% statistically optimized 6 mm, 25% random 6 mm, 25% statistically optimized 5 mm, and full array 5 mm.
