SYNTHETIC APERTURE RADAR SYSTEM FOR AIRCRAFT OR SPACECRAFT

摘要

PROBLEM TO BE SOLVED: To provide an SAR system increased in an image band width at high resolution without having a significant system loss, capable of reducing a size of a transmission antenna, and useful, in particular, for systematic image- pick-up for the surface of the ground. SOLUTION: In this radar system for an aircaft or a spacecraft having a synthetic aperture radar, the transmission antenna 3 by a bistatic radar and a receive antenna 21 are provided to make one of them arranged in a moving different platform separated physically in an upper side of the ground, so as to generate relative movement between the transmission antenna 3 and the receive antenna 21. Either or both of the transmission antenna 3 and the receive antenna 21 is/are constituted to conduct ambiguity control.
