Probability density function and the speckle number on Receive Aperture
We develop an analytical expression for probability density function of speckle intensity on receiving aperture and express integral speckle intensity variance when receive aperture area is s. Analytical and numerical results of speckle number are given for rectangular and circular diffuser apertures. Laser radar intensity image are simulated in different speckle numbers on receive aperture. The results shows that the image is becoming more and more clearly as speckle numbers increase by the increasing of receiving aperture and decrease of the light beam waist.
