The sea state bias (SSB) has become the dominant source of error in satellite altimetry. The operational SSB correction models are two-dimensional (2-D) nonparametric models based on the wind speed (U) and the significant wave height (SWH) that can be directly measured by the altimeters. This paper estimates the sea state bias of HY-2A radar altimeter using a three-dimensional (3-D) nonparametric...
Significant wave height (SWH) is one of the major ocean altimetry products. This paper proposes a fast algorithm in retrieving the SWH from altimeter waveform. The idea is to differentiate the echo waveform and acquire a Gaussian-shape waveform. Then the standard deviation of the Gaussian function is computed directly and the standard deviation of the scatter probability density function (hence, SWH)...
HY-2A, the China's first satellite for oceanic dynamic environment measurement, was launched on August 16th, 2011. As one of main payloads of HY-2A satellite, HY-2A radar altimeter is a dual-frequency (Ku and C band) altimeter with a conventional pulse-limited method. The altimeter can measure sea surface height, significant wave height, and sea surface wind speed. The accuracy of the altimeter is...
HY-2A, the China's first satellite for oceanic dynamic environment measurement, was launched on August 16th, 2011. As one of main payloads of HY-2A, HY-2A radar altimeter (RA/HY-2A) has been operating stably since the launch, and obtained a lot of scientific data. RA/HY-2A is a dual-frequency (Ku and C band) radar altimeter with a conventional pulse-limited method, and some new techniques such as...
Satellite radar altimeter is an active microwave remote sensor for obtaining ocean topography, as well as the marine and land ice mass fluxes at a global scale. Because the echo properties of ocean, land and pole ice are very different, the on-board tracker of radar altimeter should have the ability to handle the distinct signals automatically. In this paper, a new tracker for ocean land compatible,...
