Abstract

Experimental studies of the properties of radio-absorbing materials and coatings to solve the problem reducing the radar visibility of aviation complexes occupy a unique position. Foreign and domestic experience shows that without development of laboratory-polygon base to achieve significant results on this issue is impossible. One of the main problems in experimental research within the problem of reduction the radar visibility is the study of electro-physical parameters of radio-absorbing material such as, complex permittivity and permeability, wave resistance and coating thickness.

The purpose of research is to develop a laboratory stand for research of electrophysical parameters of radio-absorbing materials and coatings.

The principle of operation of the laboratory stand is based on the effect «spill» slow surface electromagnetic waves on a plane surface and scan results from the interaction of the field with a coating layer in the functions of the complex electro-physical and geometrical parameters (permittivity and magnetic permeability and thickness of the coating)

As a result of theoretical and experimental studies designed laboratory bench for the study of electrophysical parameters of radio-absorbing materials and coatings. The advantages of the proposed device is to provide non-contact measurement, high efficiency and accuracy of measurements, a large number of simultaneously monitored parameters, low cost primary transmitter and at least elements of the device.

The resulting specifications developed by the laboratory stand can effectively use it in the study of electro-physical parameters existing and emerging models of radio-absorbing materials and coatings aviation complexes . Besides laboratory bench can be used as a basis for the design and development of modern equipment for controlling the parameters of radio-absorbing materials perspective aviation complexes with reduced radar signature.
