The monograph provides features of measuring radar characteristics of objects on experimental installations of various types. Modern and classical methods are described for analyzing the scattering properties of an aircraft and elements of its layout. A method for calculating the reflective characteristics of radar absorbent coatings is presented. Technical solutions implemented in foreign aircraft of low-reflecting forms are considered. The effect of layout solutions required to ensure a low level of radar reflection on the aerodynamic characteristics of the aircraft was assessed.
