2 Sentinel-1 SAR Imaging Modes SAR Instrument provides 4 exclusive SAR modes with different resolution and coverage Polarisation schemes for IW, EW & SM: single pol: HH or VV dual pol: HH+HV or VV+VH Wave mode (WV): HH or VV SAR duty cycle per orbit: up to 25 min in any imaging mode up to 74 min in Wave mode 2
3 Sentinel-1 SAR TOPS Mode TOPS (Terrain Observation with Progressive Scans in azimuth) for Sentinel-1 Interferometric Wide Swath (IW) and Extra Wide Swath (EW) modes ScanSAR-type beam steering in elevation to provide large swath width (IW: 250km and EW: 400km) Antenna beam is steered along azimuth from aft to the fore at a constant rate All targets are observed by the entire azimuth antenna pattern eliminating scalloping effect in ScanSAR imagery Constant SNR and azimuth ambiguities Reduction of azimuth resolution due to decrease in dwell time Sentinel-1 IW TOPS mode parameters: ±0.6 azimuth scanning at Pulse Repetition Interval with step size of 1.6 mdeg. Sentinel-1A IW dual-pol image, acquired over Namibia 3
4 Sentinel-1A IW TOPS InSAR Repeat-pass TOPS InSAR using Interferometric Wide Swath (IW) data pairs worked on the spot 250km S-1A IW interferogram of data pair acquired 7-19 August, 2014 (2π height = m) Verification of: SAR instrument phase stability Satellite on-board timing and GNSS solution to support position-tagged commanding (OPS angle) Mission Planning system using TOPS cycle time grid points for datatake start time estimation Accurate orbit control (orbital tube) Burst synchronization 1200 km 4 Image courtesy, DLR-IMF
5 Datatake Start Time Estimation for Burst Synchronization Position-tag Commanding Data acquisition (repeat orbit cycle) over the same ground location uses on On-board Position Schedule execution (OPS) based on Orbit Position angle (instead of timing) Advantage: more accurate DT start time estimation no need for precise orbit prediction or frequent update of on-board command queue First imaging PRI t echo α PVT αα α start_plan Calculation of OPS angle α start_plan based on : using actual S-1A orbit position OPS angle - S-1A Reference orbit - use of an orbital point grid based on burst cycle time tt ~20 s Spacecraft Avionics converts (on-board) planned OPS angle (α start_plan ) to time (t start ) by analytical propagation of GPS PVT data t start time using SAR mode LUT t echo PVT (on-board GPS) Instrument executes measurement according to t start 5 Image courtesy, DLR-IMF
6 Verification of S-1A IW DT Start Time Estimation for Burst Synchronization 498 IW measurements between Aug. 7 th, 2014 (Reference Orbit reached) and Sept. 6 th, 2014 Measured performance includes: - Accuracy of the on-board conversion from OPS angles to instrument start time - Accuracy of instrument in achieving the requested start time Average = 1.32 ms Std dev = 1.28 ms Duration of IW bursts: IW1: 0.8s IW2: 1.06s IW3: 0.83s 6 Image courtesy, DLR-IMF

10 Sentinel-1A Orbital Tube Reference orbit was reached on August 7 th, 2014 Satellite is kept within an Orbital Tube around a Reference Mission Orbit (RMO) Initially specified Orbital Tube radius of 50 (rms) equivalent to Ground-track dead-band of 60m During S-1A Commissioning: Relaxation of Ground-track dead-band to 120m Orbital Tube radius of better than 100 (rms) after adjustment of orbit Eccentricity to improve alongtrack baseline RMS of Orbital Tube w.r.t.

14 Sentinel-1A Observation Scenario Tectonic and Volcanic Areas BLUE: Acquisitions in IW dual pol mode, VV+VH polarisation, every 12 days ascending and descending BLACK: Acquisitions in IW mode, VV polarisation, every 12 days ascending or descending; repeat on the same track every 24 days Stripmap mode (SM) acquisitions over selected small volcanic islands All Land and Ice masses systematically provided as IW SLC data products Includes all global tectonic/volcanic areas About 1.4 TB of IW SLC data available daily Increased sampling density over supersites outside Europe About one third of global landmass regularly covered, based on this acquisition strategy 14
15 Elevation Antenna Pattern Phase Correction in IPF v2.43 New IPF version 2.43 (since end of March 2015) applies a complex Elevation Antenna Pattern (EAP) correction for inter-channel phase correction in support of polarimetry applications Previous versions of the IPF did not correct for the EAP phase Interferogram between SLC data generated by previous and current IPF (2.43) version shows phase ramps in range, and eventually also phase jumps between sub-swaths. EAP is annotated in SLC product (in complex format for the new IPF version) Proposed Correction: Calculation of complex EAP for SLC data processed before end of March 2015, as outlined in TN by PDGS Alternative Correction: Undo EAP phase correction of SLC products, processed since March 2015 using the annotated complex EAP IPF 2.36 vs IPF 2.43 (EAP phase removed) Similar Issue with proposed Bistatic Correction in the IPF which implies introducing a range-dependent azimuth shift Images courtesy P. Prats, DLR azimuth range 15
16 Conclusions Sentinel-1 acquires systematically and provide routinely SAR data for operational monitoring tasks for Copernicus (GMES) and national EO services Using the same SAR imaging mode (instrument settings), e.g. IW mode, facilitates the build-up of long data time series for continuous observations with equidistant and short time intervals (interferogram stacks) Sentinel-1 A & B will fly in the same orbital plane with 180 deg. phased in orbit, each with12-day repeat orbit cycle Formation of InSAR data pairs having time intervals of 6-days Small orbital tube with radius of < 100m (rms) provides small InSAR baselines TOPS burst synchronization and small Doppler centroid differences enable wide-area SAR Interferometry Coherent Change Detection monitoring Collaboration with Canada s RADARSAT Constellation Mission (RCM) to facilitate multi-satellite SAR monitoring requires harmonization of data acquisition strategies 16

18 Sentinel-1 Orbital Tube and InSAR Baseline S-1A & B Satellites will be kept within an Orbital Tube around a Reference Mission Orbit (RMO) Orbital Tube radius with <100m (rms) Orbit control is achieved by applying across-track dead-band control at the most Northern point and Ascending Note crossing Sentinel-1 A & B will fly in the same orbital plane with 180 deg. phased in orbit 12-day repeat orbit cycle for each satellite Formation of SAR interferometry (InSAR) data pairs having time intervals of 6-days 18
