<p>The invention concerns a method which consists in launching one behind the other on two close orbits two satellites (S1, S2) each equipped with a high-resolution synthetic aperture radar observing the Earth under an angle of incidence of at least 40°, such that the radars observe independently of each other the same strip of terrain, with a time interval of not more than 10 seconds, preferably not more than 4 seconds, preferably not less than 2 seconds between their respective observations.</p> |
