Polarization compression of large dynamic range laser returned signals from water surface and underwater

摘要

This paper describes a polarization detection method to compress a large dynamic range of laser returned signals from water surface and underwater in an airborne laser bathymetry system. The experimental results show that the method can compress the dynamic range of returned signals by more than one order of magnitude. The laser reflection on the water surface and underwater backscatter is considerably reduced without significantly affecting the laser returned signals from the underwater target. [References: 8]
