The Capella constellation will consist of 36 agile synthetic aperture radars. Each radar will operate at an altitude of around 500 km in an approximately 90-minute polar orbit, providing average imaging revisit times of less than one hour. The radars will be single-pol X-band systems, capable of operating over a 500 MHz bandwidth in stripmap and spotlight imaging modes.
