Abstract
Formerly we must predetermine the approximate value of tfe maximum range of small targets at sea from empirical data. In this paper I measure the cross sections and the effective heights of targets and from these values, approximate numerically the maximum range of targets at sea. Comparing the results of this method with the empirically measured values of the same targets, are reported the coincidence between them. As reference some measured values of cross sections and effective heights about several vessels are listed here.
