Triple

Target class: synthetic aperture radar satellite system
Context triple: [COSMO-SkyMed, instanceOf, synthetic aperture radar satellite system]

• A. spaceborne synthetic aperture radar instrument
  A spaceborne synthetic aperture radar instrument is an orbiting radar system that transmits microwave pulses and uses the motion of the spacecraft to synthesize a large antenna aperture, producing high-resolution images of Earth's surface regardless of weather or lighting conditions.
• B. remote sensing satellite
  A remote sensing satellite is an orbiting spacecraft equipped with sensors that collect data about the Earth's surface and atmosphere for applications such as mapping, environmental monitoring, and resource management.
• C. satellite system chosen
  A satellite system is an integrated network of orbiting spacecraft, ground stations, and communication links designed to perform functions such as communication, navigation, Earth observation, or scientific research.
• D. polar-orbiting satellite
  A polar-orbiting satellite is a spacecraft that travels in a low Earth orbit passing close to the poles, allowing it to observe the entire Earth's surface over time as the planet rotates beneath it.
• E. spaceborne radiometer
  A spaceborne radiometer is an instrument mounted on a satellite that measures the intensity of electromagnetic radiation emitted, reflected, or scattered by the Earth or other celestial bodies to infer physical properties such as temperature, composition, and surface characteristics.
• F. None of above.
