Weighing 2,392 kg, NISAR is a unique Earth observation satellite and the first to observe the Earth with a dual-frequency Synthetic Aperture Radar (NASA's L-band and ISRO's S-band), both using NASA's 12m unfurlable mesh reflector antenna, integrated to ISRO's modified 13k satellite bus.
It will observe Earth with a swath of 242 km and high spatial resolution, using SweepSAR technology for the first time, according to the space agency.
