RISAT-2, or Radar Imaging Satellite-2 was an Indian radar imaging reconnaissance satellite that was part of India's RISAT programme. It was built by Indian Space Research Organisation (ISRO) and successfully launched aboard a PSLV-CA launch vehicle at 01:15:00 UTC on 20 April 2009 from the Second Launch Pad at the Satish Dhawan Space Centre.[5]

The principal sensor of RISAT-2 was an X-band synthetic-aperture radar (SAR) from Israel Aerospace Industries (IAI).[6] It is designed to monitor India's borders and as part of anti-infiltration and anti-terrorist operations.[7] The satellite has a mass of 300 kg (660 lb).
