His approach allows the detailed analysis of combined effects of diffraction, refraction and scattering in random media. While specific applications covered are targeted at radio wave propagation over the sea surface, a similar approach is applicable to many problems in underwater acoustics, seismology, solid matter physics and astrophysics. 606 $aRadio wave propagation$xMathematical models 606 $aRadio wave propagation$xComputer simulation 615 0$aRadio wave propagation$xMathematical models. 615 0$aRadio wave propagation$xComputer simulation. 676 $a621.38411 700 $aKukushkin$b Alexander$01637320 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911019743003321 996 $aRadio wave propagation in the marine boundary layer$94422181 997 $aUNINA
