ISRO to launch radar imaging satellite (RISAT)

India is all set to launch a radar imaging satellite (RISAT) built with "substantial inputs" from the Israel aerospace industry from Sriharikota spaceport, an ISRO official said on Friday.

Israel has supplied Synthetic Aperture Radar (SAR), which is in fact "heart" of the 1780-kg remote sensing satellite. Israel has supplied substantial systems," an 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 5th or 6th April.

An active sensor, SAR operates in the microwave range of electromagnetic spectrum and provides the target parameters such as dielectric constant, roughness, and geometry.
