Computation of the Noncentral F Distribution (CFAR)Detection

A formula is given that enables accurate values of the cumulative noncentral F distribution to be calculated. Since it does not seem to be generally known that constant false alarm rate (CFAR) detection problems are concerned with evaluating the noncentral F distribution, results using the algorithm are compared with published values obtained using a CFAR algorithm. Both engineers and statisticians are therefore encouraged to consult each other's publications for useful (though maybe disguised) material.
