2 Main Mission Objectives: Mapping the Dynamic Earth Biosphere 3-D vegetation monitoring measurement of forest height and structure global inventory of above ground forest biomass vegetation disturbances and biomass changes Geo/Lithosphere deformation measurements understanding earthquake and volcano eruption cycles quantifying the magnitude of events determination and forecasting the probability of events Hydro/Cryosphere observation of ice structure and its changes measurement of soil moisture and surface water changes monitoring of ocean currents and wave field dynamics 2
3 3D Structure Mode Polarimetric SAR Interferometry (Pol-InSAR/single-pass) ~ 30 m Estimation of the vertical structure of volume scatterers: Vertical structure components are resolved by means of their polarimetric signature; The (height) location of the resolved structural components is estimated by interferometric measurements. 3
4 Performance Prediction: 3-D Structure Mode (Pol-InSAR) k z = 0.05 rad/m (h amb = m) k z = 0.2 rad/m (h amb = 31.4 m) k z = 0.1 rad/m (h amb = 62.8 m) Model Model = RVoG RVoG = db/m db/m sys 0.9 sys = 0.9 N look 30 look = 30 multiple acquisitions with different baselines 4
5 Deformation Mode Earthquakes measurement of deformations of mm cm Volcanoes λ/2 12 cm Subsidence Land & Sea Ice systematic multi-temporal acquisitions (image stacks) 5
6 Performance Example: Deformation Mode combined error T T = 8 days days = days days a 10 mm a = 10 mm SNR SNR = db db N look 32 look = 32 Conclusions: SNR temporal decorrelation atmosphere as many looks as possible (high res.) as many data takes as possible SNR not so critical (e.g. coarse quant.) 6
7 Mission and System Requirements measurement of 3-D structures (vegetation) & their evolution monitoring of geo-dynamics (deformation) with high temporal resolution L-band SAR single-pass interferometry (satellite formation) full polarimetry wide-swath and highresolution SAR imaging high downlink capacity (e.g. Ka-band network, geostationary relay, ) 7

10 Equator: Horizontal Baselines (Bistatic Mode) h=800 km h=700 km h=600 km k z =0.2 rad/m (h amb = 31.4 m) B h = m k z =0.1 rad/m (h amb = 62.8 m) k z =0.05 rad/m (h amb = m) 10
11 Ascending Node Drift by Different Inclinations (h=700km) Δi 2 km (Δv<2.4 m/s) 1 km (Δv<1.2 m/s) 500 m (Δv<0.6 m/s) ΔΩ 200 m (Δv<0.3 m/s) mission concept with varying baselines by slight inclination shifts 11
12 Baselines at high latitudes (bistatic mode) inclination differences between the orbital planes Δi horizontal baseline vertical component from eccentricity vector differences (limited) radial baseline Δe use of alternating bistatic (monostatic baseline) narrower swaths: optimum positioning vs. incidence 12
13 Tandem benefits for repeat-pass interferometry frozen orbit satellite variable orbit satellite use (zero baseline) looking right looking right DEM from single-pass (L-band!) right-looking series looking right looking left, baseline fixed for 2 repeat-pass cycles uninterrupted rightlooking series interferogram from leftlooking geom. (3D) looking left looking left time series from leftlooking geom. (3D) DEM from single-pass looking right, reduced bandwidth, full swath looking right, large bandwidth, reduced swath conflict resolution with other applications 13
