- A review of altimetry waveform retracking for inland water levels
We evaluate and compared key strategies from prototype retrackers to improved retrackers, especially the empirical ones optimized for inland waters Sub-waveform extraction and adjustment for Delay-Doppler modes has advanced range retrieval to a new stage
- Wavelet decomposition and deep learning of altimetry waveform . . .
Satellite altimetry (SA) together with the advanced precise orbital positioning system has reached a high accuracy in the measurement of the water level height, but increasing the accuracy of waveform retracking (WR) is a challenging issue
- A review of altimetry waveform retracking for inland water levels
We evaluate and compared key strategies from prototype retrackers to improved retrackers, especially the empirical ones optimized for inland waters Sub-waveform extraction and adjustment for Delay-Doppler modes has advanced range retrieval to a new stage
- Improving Inland Water Altimetry Through Bin-Space-Time (BiST . . .
Here, we propose the bin-space-time (BiST) retracking method that moves beyond finding a single point in a 1-D waveform and instead seeks a retracking line within a 2-D radargram, for which the temporal information over different cycles is also considered
- A review of altimetry waveform retracking for inland water levels
Villadsen, Improved inland water levels from SAR altimetry using novel empirical and physical retrackers, J Hydrol , № 537, с 234 DOI: 10 1016 j jhydrol 2016 03 051
- Improving inland water altimetry retracking by incorporating spatial . . .
Developing a retracking method that benefits from the spatio-temporal variation of power in a radargram stack The retracker offset obtained from the radargram stack: • benefits from the spatio-temporal correlation of recorded power • less sensitive to noisy waveforms • less influenced by blunders • independent from a prescribed
- Analysis of Sentinel-3 SAR altimetry waveform retracking algorithms for . . .
In this research, we aim to evaluate the performances of different SRAL SAR retrackers in retrieving lake water levels in a full hydrologic cycle, assess the effect of the lake ice cover on the returned SAR altimetry waveforms and associated measurement error in lake level retrieval in winter season, and develop a new bimodal correction
- Lake Level Variations Monitored With Satellite Altimetry Waveform . . .
To improve altimeter ranging accuracy and in turn to get better surface height measurement, contaminated waveforms should be retracked against geophysical corrections In this paper, an improved
