Last week, the American space agency NASA made an announcement. They stated that they counted the days to implement the most advanced and high-tech radars on our planet. The multi-advanced world surveillance satellites, called NISAR, will begin to use the most advanced radar technology ever made to present unprecedented images of our planet.
NISAR is a satellite task called NASA-isa-Isro Synthetic Aperture Radar). This task is carried out together by NASA and Indian Space Research Organization (ISRO). NISAR will use synthetic opening radar (SAR) technology to obtain high-resolution images of the world's surface.
NISAR will be used to monitor global changes on the surface of the Earth and the effects of natural disasters. In particular, it will be used to monitor soil movements, changes in glaciers, the status of forests, and the efficiency of agricultural areas and water resources. It can also be used to monitor atmospheric events, as SAR technology is suitable for obtaining high-resolution images even in cloudy weather.
SAR (Synthetic Aperture Radar) is a radar imaging technique used to obtain high-resolution images. SAR sends high-frequency radio waves to the earth from a moving platform such as satellites, aircraft, or ground stations and maps the surface properties of the earth by measuring the properties of the reflected waves.
SAR technology is important for NISAR because it measures the signals reflected according to the different characteristics of objects and surfaces on Earth and obtains high-resolution images. In this way, changes and movements on Earth can be identified and used by scientists and experts in many fields. For example, an early warning of natural disasters such as forest fires or flood disasters can be made with SAR technology. In addition, research can be conducted on issues such as changes in SAR and coastal regions, melting of glaciers, desertification, groundwater resources, and ground shell movements. Using this technology, Nisar will provide information in many areas by examining the changes in different parts of the earth.
NISAR is planned to be launched in 2023.
