Suppression of Parasitic Peaks on CFOSAT SWIM Wave Spectra Based on a Specific Parametric Method

Remote Sensing
Parasitic peaks are observed in the low wavenumber regions of Surface Waves Investigation and Monitoring (SWIM) wave height spectra. They can be attributed to random fluctuations in the wave spectra caused mainly by speckle noise, compromising the ...

CFOSAT散射计海面后向散射系数误差及影响

Kongjian kexue xuebao
仪器噪声(Kpc)和地球物理噪声(Kpg)是影响星载微波散射计后向散射系数(σ0)测量精度以及海面风场反演精度的关键因素. 针对中法海洋卫星(CFOSAT)散射计(CSCAT), 详细分析了Kpc和Kpg随海面风速、入射角、风单元网格分辨率以及离岸距离等因素变化的特征. 结果表明, 低风速条件下海面风场变异性较大, Kpg为σ0测量误差的主导因素, 而且风单元网格越大、海面风场的不均匀性越强, Kpg也就越大, 而在高风速条件下, 海面风场变异性较小, Kpc与Kpg贡献相当.
