Abstract :
Imaging of space objects in orbit using space-borne millimeter wave Inverse synthetic aperture radar (ISAR) is investigated. The geometrical and kinetic relationship between the space-borne radar and the object is analyzed. Range walk and range dispersion have occurred during the pulse duration, caused by the high-velocity radial motion. A novel method for radial velocity compensation based on radon-ambiguity transform (RAT) is proposed. Computer simulation illustrates the feasibility of imaging space objects using space-borne radar.
