1. A method, comprising:
receiving, from a radar station, a tasking request comprising a location of an imaging target, a target velocity range, and satellite positioning maneuvers based on the location and the target velocity range;
transmitting, from a main satellite comprising a synthetic aperture radar, at least a radio frequency pulse to illuminate the imaging target;
receiving, from two or more additional satellites configured to fly in-formation with respect to at least the main satellite, at least an echo of the radio frequency pulse, wherein each of the two or more additional satellites include an omnidirectional Telemetry, Tracking and Command (TTC) transponder;
generating synthetic aperture radar image data based at least on the echo;
communicating the synthetic aperture radar image data to the main satellite; and
processing the synthetic aperture radar image data on one or more graphical processing units based at least on performing image formation, orthorectification, and synthetic aperture radar tomography.
