Paper Abstract

This paper presents analysis of the possibility to design all-weather pulse laser altimeters for measuring lowaltitudes above the sea surface. We proposed special design features which consider the low reflection coefficient and the reflective properties of random rough sea surface. Backscattering by fog with various density was analyzed. With considering the reflection coefficient from the sea surface less than 4%, we proposed measurement method based on the drop of the backscattering signal. We examined the measurement range and measurement errors depending on the transfer function of the receiving-amplifying circuit for inertial and non-inertial detection. The energy compensation for specified measurement precision was carried out.
