Systems and methods in accordance with various embodiments of the present disclosure provide high efficiency synthetic aperture radar satellite designs that achieve higher power efficiency and higher antenna aperture size to satellite mass ratios than the current state of the art. In various embodiments, a high efficiency synthetic aperture radar satellite includes a satellite bus and a parabolic reflector antenna coupled to the satellite bus. The satellite system may further include a traveling wave tube amplifier configured to drive the parabolic reflector antenna, and a body-mounted steering system configured to mechanically steer the satellite system to direct the parabolic reflector antenna. The satellite system may further include a processor configured to combine the pulse reflections and generate image data representing the region of interest, in which the image data is effectively obtained with a synthetic aperture greater than the actual antenna aperture.
