RISAT (Radar Imaging Satellite) is a series of Indian radar imaging reconnaissance satellites built by ISRO. They provide all-weather surveillance using synthetic aperture radars (SAR). The RISAT series are the first all-weather Earth observation satellites from ISRO. Previous Indian observation satellites relied primarily on optical and spectral sensors which were hampered by cloud cover. After the 26 November 2008, 2008 Mumbai attacks, the launch plan was modified to launch RISAT-2 before RISAT-1, since the indigenous C-band SAR to be used for RISAT-1 was not ready. RISAT-2 used an Israel Aerospace Industries (IAI) X-band SAR sensor similar to the one employed on TecSAR.

Mereka menyediakan semua pengawasan cuaca menggunakan radar aperture sintetis (SAR). Seri Risat adalah satelit observasi cuaca bumi yang pertama dari ISRO. Sebelumnya satelit observasi India mengandalkan terutama pada sensor optik dan spektral yang terhambat oleh awan. Setelah November 26, 2008 serangan Mumbai, rencana peluncuran dimodifikasi untuk meluncurkan Risat-2 sebelum-Risat 1, karena SAR C-band yang akan digunakan untuk-Risat 1 tidak siap. Risat-2 menggunakan sebuah Israel Aerospace Industries (IAI) X-band sensor SAR mirip dengan yang digunakan pada TecSAR.

RISAT 시리즈는 인도우주연구기구의 첫번째 전천후 지구 관측 위성으로, 이전 세대의 관측 위성은 구름의 운량에 따라 관측에 방해를 받을 수 밖에 없는 광학 및 분광 센서를 사용하였다. 2008년 뭄바이 테러가 벌어진 2008년 11월 26일 이후, RISAT-1에 탑재할 자국산 C-밴드 합성개구레이다가 개발 중이었기 때문에, 이스라엘 항공우주 산업에서 제작한 X-밴드 합성개구레이다를 탑재한 RISAT-2가 먼저 발사되었다.
