Abstract

The work is dedicated to the analysis of spatial energy characteristics of geodetic passive glass satellites of the BLITS type for high-precision laser ranging. The article covers principles of calculation of a retroreflector spherical system (RSS), which appears to be a set of concentric layers with different refractive indices. The peculiarity of the performed analysis allows for the specifics of the RSS space application requires maximum reflected power towards the receiver determined by the phenomenon of light velocity aberration. The reflected coherent laser radiation produced by the RSS in the far zone has been analyzed using the Zemax program. An equation is derived to estimate the spatial energy characteristic (cross-section) of the BLITS-type satellites. The authors introduce the concept of an effective diameter for the output beam, which generates a far-field diffraction pattern.
