Abstract :
Approximations are derived for the statistical functions that characterize the matched filter output amplitude given a non-fluctuating point target and an arbitrary clutter model. The approximations are the inverse Hankel transform of a Pade approximation to their associated characteristic functions (CF) and can be used to calculate receiver operating characteristics (ROCs)
