Abstract

In the radio optically active detection and ranging of objects a signal from an investigated object at the noise background should be recognized. This noise may be the background created both by a foreign source and the background from the underlying surface, on which the object being studied is located. Using the source polarization of a sensing signal of optical radar and polarization elements of the receiver, we can increase the value of the signal from the studied object as compared with the noise background. The versions of the efficiency increase of research tools of active radio and optical sensing are considered at the following conditions: 1. The background from the external source is known. 2. The scattering matrix of underlying surface creating the background is known. 3. The scattering matrix of underlying surface creating the background is unknown. 4. The external source and underlying surface present the background source: a) the Stokes vector of external source and the scattering matrix of underlying surface are known; b) the Stokes vector of external source and the scattering matrix of underlying surface are unknown; c) the Stokes vector of external source is known and the scattering matrix of underlying surface is unknown and vice versa.
