Israel has supplied Synthetic Aperture Radar (SAR), which is in fact “heart” of the 1780-kg remote sensing satellite, the official told PTI on condition of anonymity. “Israel has supplied substantial systems,” the ISRO official said.
The Israeli “inputs” are seen as a “return gesture” by the Jewish State to New Delhi for launching an Israeli spacecraft Techsar on board India’s Polar Satellite Launch Vehicle from Sriharikota last year.
“RISAT is likely to be launched in the first half of April. We are looking at April five or six,” the official said.
An active sensor, SAR operates in the microwave range of electromagnetic spectrum and provides the target parameters such as dielectric constant, roughness, and geometry.
