Numerical analysis of holographic images degraded by turbulence in consideration of the double passage effect

In radar imaging the authors consider the double passage effect under a strong turbulence model, the authors have analyzed holographic imaging and evaluated the effect on the imaging. Some numerical analyses show that the double passage effect produces an intensity enhancement at the center of the image of size larger than the wavelength of an incident wave. The authors trying to restore the image distortion and improve the image resolution by applying a filtering technique.
