metallic parts. Based on the assumption that only moving, metallic parts of a turbine cause echoes indelible by standard filtering used in radar signal preprocessing, a method of preliminary evaluation of such maximum potential clutters was developed. The method takes into account how great a part of a turbine is really illuminated by a radar beam and for this part calculates a RCS (Radar Cross Section) and its equivalent radar reflectivity. A very detailed description of the model is given in this article in order for it to be easy to implement in any calculation system. Discussion of the influence of the main simplifications assumed in this model, as well as a comparison of the theoretical results with example data in operational mode of radar work, are included in this article.
