DETECTION OF CHI-SQUARE FLUCTUATING TARGETS IN ARBITRARY CLUTTER

In a recent paper, general expressions were derived for the density an d cumulative probability functions of the amplitude of a linear matche d-filter output given a nonfluctuating target in a clutter-limited env ironment. These expressions were based on the clutter amplitude densit y function. The results are extended to calculate the cumulative proba bility function of the output of a linear matched filter used to detec t a chi-square fluctuating target in a clutter-limited environment. Th e resulting method is applied to a common radar clutter model, and exp erimental sonar data.
