It has been developed method for detecting moving objects behind leaves of trees and shrubs based on the use of entropy of the phase structure of reflected signals in the frequency range 1200 - 1400 MHz.It have been developed the principle of increasing the efficiency of radiation and receiving of magnetic antennas for subsurface probing problems at comparatively big depths (over hundreds of meters) in the frequency range 0.5-5 MHz. It has been developed technique for creating a digital profile of the surface of wind sea waves for radiophysical problems to determine the electromagnetic field scattered from. It has been developed and investigated the methods of spectral estimation MUSIC and MATRIX PENCIL for the problem of increasing the accuracy of measuring the elevation angles of low altitude targets in the conditions of multipath interference and thermal noise. It has been developed technique for processing statistical results in problems of scanning tomography based on the algorithmic theory of information, for processing statistical results in problems of scanning tomography, It has been developed "two-frequency" single-valued heterodyne millimeter-wave interferometer to measure the linear integral electron concentration of high-temperature plasma in a two-diode 8-mm autodin on Gunn diodes for use in process control systems. It was carried out researches of influence of a condition of an integument of the person on characteristics of own radio-thermal radiation in millimeter range of radio waves. The emission properties of metallic stained materials in the 3-mm range of radio waves are investigated in the presence of damage to paintwork and the appearance of rust on the surface of the metal for operational monitoring and diagnostics of the state of various industrial metal objects.5481 Product Description popup.authors Єрмак Г.П.
