Single-input Single-output SAR-FFT for Fast Multistatic Millimeter Wave Imaging

In this paper, fast multistatic millimeter wave imaging (MMWI) is considered. A single-input single output (SISO) SAR-FFT algorithm using significantly less data is proposed. The novel algorithm implements SISO configuration to acquire echo data. Such a scheme leads to faster acquisition of less data and faster reconstruction at negligible cost of image quality. It has been validated by both synthetic and experimental imaging.
