Abstract :
This paper investigates the correlations between sensor signals in multipath environments created by correlated scatterers. We derive a closed form expression for the correlation in fields created by arbitrary scatterer correlations and scatterer powers, using Fourier techniques, and propose reasonable function forms for scatterer correlation. Simulations show notable differences from the uncorrelated scatterer case
