Currently, an urgent task is to reduce the radar signature of unmanned aerial vehicles (UAVs). The solution to this problem is possible through the use of radio-absorbing materials (RAM) in the design of the UAV, which make it possible to reduce the radar signature of the UAV by reducing the effective scattering area. Systematization of the general principles for selecting RAM for UAVs, taking into account the specifics of this class of aircraft: weight and size limitations, frequency range, variety of operating conditions. The physical foundations of the functioning of radio-absorbing materials are considered, their classification by absorption mechanisms and design is presented. The frequency dependences of the reflection coefficient on various types of RAM are given. The principles for choosing the optimal type of RAM for UAVs are determined, presented in the form of an algorithm of several successive stages. The directions of scientific research and applied research in the field of creating promising radio-absorbing materials to reduce visibility are determined. The considered principles for selecting RAM for UAVs make it possible to reasonably select RPM depending on the frequency range, weight and size restrictions and operating conditions of the UAV.
