Abstract :
The double weighted Fourier transform (DWFT) is proposed for eliminating intensity fluctuations of waves propagating in random inhomogeneous media. Effects of sizes of receiving and transmitting antenna systems on fluctuation reduction at the given spatial processing of the wave field in modes of both weak and strong intensity fluctuations are under study. Efficiency of the fluctuation reduction by the inverse DWFT at finite sizes of receiving and transmitting antenna systems is shown to be determined by the relation between their sizes and the Fresnel radius.
