In this paper, the angular noises of the rotating blades of a radar object are considered. A multipoint geometric model of rotating blades of a single propeller is considered. On its basis, analytical expressions are obtained that make it possible to calculate the angular coordinates of the apparent center of radiation of a propeller with rotating blades. Also, on the basis of a multi-point geometric model, relations were obtained that make it possible to synthesize a two-point geometric model of rotating propeller blades. Theoretical results are confirmed by mathematical mode¬ling for two configurations of a single-rotor small-sized aircraft: with one rotating blade and with two rotating blades.
