GENERAL EXPRESSIONS FOR RICIAN DENSITY AND DISTRIBUTION-FUNCTIONS

General expressions are derived for the density and distribution functions of the amplitude of a linear matched filter output given a nonfluctuating target in arbitrary clutter. These generalized Rician density and distribution functions are based on the density function of the clutter amplitude at the receiver output, and are easily evaluated numerically. Furthermore, we present error bounds for the numerical calculation of the density function. We also present several numerical examples.
