Abstract

The recent surge in the application of millimeter-wave sensing for public security has been accompanied by deployments of whole-body scanners at airports and stations. Some exiting imaging apparatuses using a synthetic aperture which requires a large number of measurements to meet the requirement of half-wavelength spacing and thus put a stringent requirement on hardware design. In this paper, we proposed a novel sparse synthetic algorithm that applies a multistatic scheme to the coprime measurements. It replaces every monostatic radar by a pair of separated transmitter and receiver along with phase corrections. Due to the multiplexing of all transmitters and receivers, the multistatic scheme further reduces the number of measurements and the amount of data to about 0.3% of the standard SAR. The efficacy of the proposed method is demonstrated using simulations and experiments.
