Advance in marine technique and application research of airborne hyperspectral remote sensing in China

Airborne hyperspectral remote sensing technique has advantages of flexibility, wide coverage and high spatial and spectral resolution, so is suitable for the coastal water environment monitoring. This paper summarizes the techniques and their applications of marine airborne hyperspectral remote sensing in China. As far as the techniques are concerned, the characteristics of PHI, a spectrometer imager fit for marine application are introduced. Concerning applications, with an aim at the difficulties in airborne remote sensing monitoring, such as the identification of red tide organism species, detection of oil film and the calculation of sea ice intensity, a detailed description is given to the application level of airborne hyperspectral remote sensing in China. Based on the requirement of national marine environment and disaster monitoring and the development trend of marine airborne remote sensing, the operational application prospect of marine airborne hyperspectral remote sensing is given.
