1. A method for combined forward and inverse synthetic aperture LADAR imaging comprising:
scanning a non-stationary target by emitting an optical signal from a non-stationary laser source; receiving, by a receiver having a real aperture, one or more reflections of the optical signal from the non-stationary target, wherein the one or more reflections are received over an observational duration; and determining, by a processor, an angular resolution θres of a synthetic aperture of the receiver in an azimuth direction according to a wavelength λ of the optical signal, a velocity vector {right arrow over (V)} of the non-stationary laser source, an angle θ measured between an axis perpendicular to {right arrow over (V)} and the non-stationary target, an angular velocity vector {right arrow over (Ω)} of the non-stationary target, a distance R between the non-stationary laser source and the non-stationary target, and the observational duration TSA; wherein the angular resolution of the synthetic aperture of the receiver in the azimuth direction is narrower than an angular resolution of the real aperture of the receiver in the azimuth direction. |
