Paper Abstract

Enhanced self-heterodyne synthetic aperture imaging ladar (SAIL) is based on the down-looking SAIL, with a transmitter of two coaxial polarization-orthogonal beams of spatial parabolic phase difference and a receiver of heterodyne detection. Enhanced self-heterodyne SAIL has the capability to eliminate the influence from the atmospheric turbulence, has a high advantage in the detection of weak signals. However, the relative movement of target and lidar platform will generate ghost image in enhanced self-heterodyne SAIL. The image process of ghost image is mathematically detailed and simulated, the results image as the theoretical analysis. The enhanced self-heterodyne SAIL is necessarily work in spotlight mode in order to eliminate ghost image for far-distance lidar imaging.
