Zusammenfassung:	A system and method for generating high-resolution imagery using electromagnetic signals includes a moveable vehicle and a multiple-input multiple-output (MIMO) radar system carried by the vehicle. The MIMO radar system includes an antenna array having a plurality of antenna elements. One or more of the antenna elements transmits electromagnetic signals towards a target area and one or more of the antenna elements receives back-scattered electromagnetic signals reflected from the target area. The system generates high-resolution three-dimensional imagery based on back-scattered electromagnetic signal data with system performance characterized by: (a) down range resolution ΔR; (b) cross-range resolution ΔX; and (c) vertical resolution ΔH. The system exploits effective synthetic apertures to improve cross-range resolution ΔX and vertical resolution ΔH based on, at least in part, the movement of the vehicle along the trajectory and a width and height of the antenna array relative to the target area.
