Ya. Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description2 Report: in two books. Book 1: 169 pp., 76 ill., 8 tabl., 188 refs. Book 2: 149 pp., 64 ill., 26 tabl., 145 refs. Atmospheric boundary layer, UAV, bioimpedance, remote sensing of the Earth, earthquake, sea surface, oil, radio waves propagation and scattering, Schumann resonance. The object - electromagnetic waves in natural (Earth's atmosphere and ionosphere) and biological media. Research objectives - the acquisition of new fundamental knowledge, development of models and experimental evaluation: of radiophysical methods for the Earth's surface and lower ionosphere remote sensing; of radar signals reflected from UAV; of meteorological parameters and characteristics of radio waves in the atmospheric boundary layer in coastal areas; of the parameters of biological objects, that are essential for assessing the viability. Methods and equipment - analytical calculations, field and laboratory experiments, numerical modeling, statistical processing; millimeter radar. Results - the effect of narrow backscattering of radio waves in deserts as a sign of aeolian transportation of sand-dust mixture with subsequent air pollution was revealed; the many angle method of modeling of the oil spread on the sea surface has been improved; anomalies in the Schumann resonance spectra were detected as a result of the scattering of ELF radio waves by ionosphere perturbations from distant earthquakes; the effect of the "day-night" boundary on the accuracy of the location of lightning by measuring ELF bursts was studied; the technology of UAV recognition using the nonlinear dynamics methods was developed; a method for assessing the viability of biological tissues based on bioimpedance measurement is proposed; a method for estimating the altitude profile of the refractive index of the atmosphere from ship measurements is developed; the model of raindrops asphericity effect on radio waves absorption is developed. Application areas - radar, medicine, meteorology, communications and navigation.
