What is the primary advantage of using dual-frequency synthetic aperture radar on the NISAR satellite compared to single-frequency radar systems?
It allows the satellite to penetrate different surface materials and capture more detailed and diverse data under various environmental conditions.
It enables the satellite to communicate with two ground stations simultaneously for faster data transmission.
It reduces the satellite's overall weight and launch cost by combining two radars into one system.
