Abstract :
Aimed at the problem of the near-field imaging in real time, a near-field narrow 2-D imaging algorithm based on the combination of single-input multiple output array (SIMO) and synthetic aperture radar (SAR) is proposed. By combining a real aperture and synthetic aperture, a 2-D synthetic aperture plane which is in terms of spatial sampling to obtain the target scattering information is synthesized. Compare with 2-D real plane array, the synthetic aperture plane of the paper reduce the number of antennas. The theoretical analysis and simulation results verify the validity of the algorithm.
