Wide-swath Ocean Radar Altimeter Based on InSAR

This dissertation makes an in-depth study on Spaceborne Ocean Radar Altimeter which can monitor the ocean in all-weather conditions round the clock. It can provide the sea level height, significant wave height and backscatter coefficient of the ocean, which make it the most effective sensor of researching the marine environment dynamics and all kinds of submarine structure division. Considering conventional radar altimeter can only measure sea surface height under the satellite, this new altimeter applies the Cross-Track InSAR technique to measure the height of wide swath ocean and proposes a research program of new wide swath ocean radar altimeter which not only can satisfy the requirements of high accuracy range measurement but also has the advantage of wide swaths.
