Abstract :
The application of synthetic aperture interferometric radiometers (SAIR) to remote sensing missions was proposed in 1988 by Ruf et al. As a contribution to the topic, the author presents some results of computer-simulations. The analysis discussed focuses on the antenna properties of a synthetic aperture built up from several interferometers with different base lengths. As a reference system, an airborne sensor operating at flight altitudes of 1-10 km has been considered. The system comprises an antenna of 2.5×2.5 m and operates at 1.4 GHz with a maximum scan angle of ±30°. This configuration permits spatial resolutions down to 100 m and covers a swath of 1-10 km depending on the flight altitude
