autocorrelation coefficient ρ [1] is denoted as simply ρ for simplicity. The

noise and clutter are uncorrelated with one another.
The definition of S is

Consider the s element. Using the fact that the noise and clutter are

uncorrelated and that each is zero mean, it can be quickly concluded that

Next consider the s element

Again, the noise and clutter are zero mean and uncorrelated and the noise is
white, so that the expected values of the first three terms are zero. However, the
last term becomes the pulse-to-pulse correlation of the clutter so that

It is easy to see that s = s and that . Thus
