7. 7 Then it is time for… …a European Space Radar Constellation with: GMTI (Ground Moving Target Indication) Target detection and geographic localization It has to allow: Global visibility High coverage per day High access time Few minutes response time

8. 8 MTI MTI, preliminary antenna size for “4-90 Km/h” (X-band): –Antenna size in the elevation plane from 1.2 to 1.6 m –Total antenna size in the azimuth plane from 6 to 9 m –Two receiving sub-apertures, with displacement of 3.0 to 4.5 m. COSMO characteristics compliant with this design, but: –Development of advanced on-board processors and Rx/Tx modules –Development of ground processing Full operational constellation : –15-20 LEO satellites – 2 B€ operational system (recurring costs)
