    NovaSAR-1 new tasking

    NovaSAR-1 new acquisition data are available in two baseline acquisition modes: Stripmap – provides the highest resolution of 6 metres with up to 20 km swath selected from a 150 km field of regard, available in single polarisation. ScanSAR – has a 20 - 30 metre resolution and up to 150 km swath. Available in single polarisation. Within each of the baseline modes there are a variety of mode options that vary according to ground range resolution, incidence angles, swath width and the number of looks: Acquisition Mode Polarisation Resolution (m) Swath Width (km) Incidence Angles Number of Looks Stripmap Single: HH 6 20 16.0 – 25.38° 3 (1 range, 3 azimuth) 13 – 20 21.29 – 31.2° Single: VV 6 20 16.0 – 25.38° 3 (1 range, 3 azimuth) 13 – 20 21.29 – 31.2° ScanSAR Single: HH 20 100 15.0 - 24.66° 4 (2 range, 2 azimuth) 50 24.51 - 28.94° Single: VV 20 100 15.0 – 24.66° 4 (2 range, 2 azimuth) 50 24.51 - 28.94° Single: HH 30 150 11.29 – 25.93° 4 (2 range, 2 azimuth) 55 27.35 - 32.01° Single: VV 30 150 11.29 – 25.93° 4 (2 range, 2 azimuth) 55 27.35 - 32.01° NovaSAR-1 data are provided as a Level 2 (ARD) product as standard, but the accompanying Level 1 data may also be requested. Level 1 – delivered as reconstructed, unprocessed instrument data at full resolution. Level 2 (ARD) – delivered as a processed product with applied radiometric and geometric corrections i.e. orthorectification and spatial registration: Geocoded Ellipsoid Corrected (GEC) – Maritime and ocean applications Geocoded Terrain Corrected (GTC) – Land applications and change detection Where available, associated automatic identification system (AIS) data may be requested alongside the NovaSAR-1 data products.
