Abstract:

The time-varying correlation function for a radar sonar back-scattered noise process is determined. An approximation is made in order to obtain an expression for the power spectrum of the noise process. The correlation function and the power spectrum are both a function of the probability density that a scatter will be at range r and time t as well as the signal pulse shape. This implies that in order to minimize the noise power the signal may not be wideband but is affected by the probability distribution of the scatterers.
