The properties of the angular glint of radar reflections from the propeller hub are considered. Analytical expressions were obtained based on a known multipoint geometric model of the propeller hub to calculate the probability density function parameters of angular glint for the planes, azimuth, and elevation angle for a single-blade rotor at an arbitrary rotation angle of the head. The relations obtained for a propeller hub with a single blade are generalized to the case of a propeller hub with an arbitrary number of blades. It is shown that the angular glint of the propeller hub is a random process with periodically changing parameters. The theoretical results are confirmed by mathematical modeling.
