Abstract

The invention discloses a satellite radar altimeter tracker compatible of sea and land, which comprises a first FFT power analyzer, an MLE error discriminator, a first Alpha-Beta filter, a second FFT power analyzer, an OCOG error discriminator, a second Alpha-Beta filter and a data composing treatment unit; wherein, the first FFT power analyzer is electrically connected to the MLE error discriminator, the first Alpha-Beta filter and the data composing treatment unit. The MLE error discriminator is respectively connected with the first Alpha-Beta filter and the data composing treatment unit electrically. The first Alpha-Beta filter is electrically connected with the data composing treatment unit. The second FFT power analyzer is electrically connected with the OCOG error discriminator, and the second Alpha-Beta filter and the data composing treatment unit. The OCOG error discriminator is respectively connected with the second Alpha-Beta filter and the data composing treatment unit electrically. The second Alpha-Beta filter is electrically connected with the data composing treatment unit. The first Alpha-Beta filter is also electrically connected with the second Alpha-Beta filter.

Description

technical field [0001] The present invention relates to a satellite radar altimeter tracker, in particular to a radar altimeter tracker with a maximum likelihood tracking algorithm (maximum likelihood estimation, MLE) and a center of gravity tracking algorithm (off center of gravity, OCOG) working in parallel . Background technique [0002] The satellite radar altimeter is an important remote sensor for the measurement of the ocean dynamic environment. The products directly measured include the height from the satellite to the sea surface, the effective wave height of the sea surface and the backscatter coefficient of the sea surface. The further inversion results of the radar altimeter measurement data can be applied to Marine geophysics, ocean dynamics, marine climate and environment, sea ice monitoring, etc. Among other things, radar altimeters measure sea ice, land-sea topography, and land surface heights. Since the Skylab test in 1973, represented by the United States...
