Wave spectrum retrieval from SWIM data: speckle spectrum estimation Session: " Wave retrieval and applications "

Once the power model is elaborated, the estimation process consists in extracting the values of a few parameters from the code; these values are injected in the power model to

It can be also noted that the estimation precision does not depend on the polarization state ellipticity, in agreement with theoretical predictions plotted with a dashed error-bar for

In this study, we explore the possibility to determine the X-ray spectrum

For pixel size a that becomes comparable to the correlation length b of the speckle pattern, we can take into account correlations between integrated intensities corresponding

The estimators obtained from four images, from the OSCI and from the pro- posed method, are compared using simulated polarimetric data degraded by speckle

Figure 13 shows (a) a ground-truth directional wave spectrum esti- mated from TRIAXYS Wave Rider buoy data, (b) the estimated directional wave spectrum using the CFT-without- ISAF,

For wind speed estimation, if only the parameters derived from radar data (mean NRCS, wind direction, radar look direction, SNR, and peak wave phase speed) were used as the inputs

Figures 4.12 to 4.16 present, respectively, the normalized RMS errors for the non- directional ocean wave spectrum, mean wind direction, spreading parameter, signifi- cant wave
