RISAT 2A [ISRO]
RISAT 2 (Radar Imaging Satellite 2) is a satellite imaging mission of ISRO using an active X-band SAR (Synthetic Aperture Radar) imager to provide continuity of service for RISAT-2. The objective of the RISAT mission is to use the all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, but also for military surveillance.
RISAT 2A is larger than its predecessors due to the new X-band SAR payload configuration with an active array antenna. The SAR operates in a single polarisation and provides 0.25 m to 13.5 m ground resolution with; 450 km coverage. The satellite is built on a modified modified I-2K (I-2000) Bus.
RISAT 2A will be launched in 2020 on an indian PSLV launch vehicle.
