Abstruct-An exact analysis is carried out on the effects of noise and surface scatter multipath on the one-way ranging errors of a singlesideband tone ranging modem used in an airplane-satellite link. With appropriate redefinition of parameters the results are shown to apply approximately to double-sideband tone ranging modems at high signal/ noise and signal/multipath ratios. The theoretical results are applied to obtain numerical results on ranging error for typical system geometries and sea states and for a representative hemisphericalaverage aircraft antenna. Multipath is shown to cause larger ranging errors than previously indicated.The need for additional channel measurements is pointed out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
