NASA and ISRO have launched a new satellite mission called NISAR, which is designed to take very precise radar images of Earth's surface. To test how accurate these images are, we perform tests using radar ground reflectors at Pinon Flats Geophysical Observatory, a well-known testing site in Southern California. We compare radar data from NISAR with older data from another satellite, Sentinel-1, to see how clear and reliable the images are. We also test how well NISAR can correct for things like ionospheric interference, which can distort radar signals. These early tests help confirm how well NISAR can be used for scientific studies like tracking land movement and earthquakes.
