Abstract

The article discusses an increase in the radar contrast of two objects simultaneously observed by a ship's radar using information about the loss of power of an electromagnetic wave irradiating these objects after its interaction with their surface or internal structure. It is shown that the scattering or reflection of electromagnetic energy from the surface or from the internal volume of an object is associated with the conductivity of the object surface or the dielectric constant of a volume object, the internal structure of which consists of scattering and absorbing particles of different sizes, shapes, and dielectric constant. An algorithm is considered for determining the matrix of losses of electromagnetic energy during scattering or reflection by objects, which makes it possible to increase the contrast of objects by changing the polarization of the irradiated wave Key words - radar contrast, objects, radar observation, loss matrix, radar basis, scattering matrix, object's own basis.
