Abstract:
|
The compensation of the Doppler frequency error is important
to accurately estimate the sea height in spaceborne GNSSR
altimetry. This work presents the impact of the residual
Doppler error on the altimetric performance. The GNSS-R altimetric
observables (waveforms) are simulated with various
observation parameters, and the degradation is analyzed vs.
the Doppler errors. It is shown that the Doppler error causes a
bias, a decrease of the waveform value, and consequently the
altimetric performance degradation in accuracy and precision. |
