  • Cost-Effective Airborne SAR 
    Vavriv, D.M.; Vynogradov, V.V.; Volkov, V.A.; Kozhyn, R.V.; Bezvesilniy, O.O.; Alekseenkov, S.V.; Shevchenko, A.V.; Belikov, A.A.; Vasilevskiy, M.P.; Zaikin, D.I. (Радиофизика и радиоастрономия, 2006)
    A Ku-band airborne SAR, which is a cost effective system in terms of the development and exploitation costs, has been recently developed and tested at the Institute of Radio Astronomy of the National Academy of Sciences ...
  • Millimeter-Wave Radars for Environmental Studies 
    Vavriv, D.M.; Volkov, V.A.; Bormotov, V.N.; Vynogradov, V.V.; Kozhyn, R.V.; Trush, B.V.; Belikov, A.A.; Semenyuta, V.Ye. (Радиофизика и радиоастрономия, 2002)
    A review is given of recent activities undertaken in the Institute of Radio Astronomy of the National Academy of Sciences of Ukraine for the development of millimeter-wave radars. The radars constructed include cloud radars ...
  • Multi-Look Radiometric Correction of SAR Images 
    Bezvesilniy, O.O.; Gorovyi, I.M.; Vynogradov, V.V.; Vavriv, D.M. (Радиофизика и радиоастрономия, 2011)
    Deviations of the aircraft trajectory and instabilities of the aircraft orientation lead to non-uniform illumination of the ground by the antenna beam and, as a result, to radiometric errors in radar images obtained with ...
  • Noise Reduction Algorithm Based on Template Wavelet Coefficients 
    Bezvesilniy, O.O.; Vynogradov, V.V.; Schuenemann, K. (Радиофизика и радиоастрономия, 2000)
    In the paper, a new algorithm based on the application of template wavelet coefficients is proposed to solve the problems concerning noise reduction in the vicinity of edges in signals and images and suppressing parasitic ...
  • SAR Processing Algorithm with Built-In Geometric Correction 
    Bezvesilniy, O.O.; Gorovyi, I.M.; Sosnytskiy, S.V.; Vavriv, D.M.; Vynogradov, V.V. (Радиофизика и радиоастрономия, 2011)
    Synthetic aperture radar (SAR) systems onboard small aircrafts suffer from trajectory deviations and instabilities of antenna orientation. These kinds of motion errors lead to significant geometric distortions in SAR ...
