Radar Imaging Satellite 1A, or RISAT-1A, is a planned remote sensing satellite that is similar in configuration to RISAT-1 . The satellite is being developed by Indian Space Research Organisation (ISRO). RISAT-1A will be 3rd in series of RISAT satellites. It will be a land based mission with primary application in terrain mapping and analysis of land, ocean and water surface for soil moisture.[3]

The satellite will carry Synthetic Aperture Radar which will operate at 5.35 GHz in C-band. Synthetic Aperture Radar can be used for earth observation irrespective of the light and weather conditions of the area being imaged.[4]
Payload metrics are defined by the following parameters and areas of study
| Category | Parameters |
|---|---|
| Land | Albedo and reflectance |
| Soil moisture | |
| Vegetation | |
| Multi-purpose imagery | |
| Ocean | Ocean topography/currents |
| Snow & Ice | Ice sheet topography |
| Snow cover, edge and depth | |
| Sea ice cover, edge and thickness |
