COMPIRA (Coastal and Ocean measurement Mission with Precise and Innovative Radar Altimeter) is the Japanese new altimetry mission with X-band interferometric SAR (synthetic aperture radar). Mission purpose is to measure the sea surface height of which become one of the key imformations on bathymetric feature, sea water temperature and ocean currents.
We will use wide-swath altimeter in order to maximize spatial coverage of the altimetry measurement and to reduce error of the tidal model in the shallow marginal seas. We have a plan to develop X-band interferometric SAR, SHIOSAI (SAR Height Imaging Oceanic Sensor with Advanced Interferometry) with two antennas. Requirement for spatial resolution is 5 km, that for swath width per each side is 80 km (totally 160 km swath).
We are now on conceptual study of the SHIOSAI. To minimize rain attenuation and maximize data acquisition around Japanese coast, we use X band (center frequency of 9.6 GHz). To satisfy the requirement for measurement accuracy, we set the radar parameter such as transmission power, band width, baseline size, and so on.
In the paper, we will present current status of conceptual study of SHIOSAI sensor. |
