Aiming to enhance India's defence surveillance capabilities, ISRO on Monday morning launched its first Radar Imaging Satellite (RISAT)
from Sriharikota.
As per specifications, RISAT is different from previous remote sensing satellites as it uses Synthetic Aperture Radar (SAR), equipped with many antennas to receive signals that are processed into high-resolution pictures.
The SAR, developed by Israel Aerospace Industries, gives RISAT defence capabilities.
