| Definition | Poseidon-2 is a radar altimeter designed to measure ocean topography, significant wave height and surface wind speed. It is also able to measure the amount of rain in the atmosphere. The Poseidon-2 altimeter emits a radar beam that is reflected back to the antenna from the Earth's surface. Poseidon-2 operates at two frequencies (in the Ku and C bands) to determine atmospheric electron content, which affects the radar signal path delay. These two frequencies also serve to measure the amount of rain in the atmosphere. Poseidon-2 operates at 13.6 GHz in the Ku band and 5.3 GHz in the C band. It has a pulse duration of 105 microseconds and a bandwidth of 320 MHz. The altimeter is nadir-only viewing, sampling at 30 km intervals along-track. Flown on JASON-1. http://www.aviso.altimetry.fr/en/missions/past-missions/jason-1/instruments/poseidon-2.html |
