Abstract : Methods and equipment were designed to measure atmospheric attenuation low over the sea surface at W Band (94 GHz). Measurements were carried out at the NRL's Chesapeake Bay Detachment, and the results were compared with theoretical values. The method described will provide accurate ships' RCS measurements at W Band, taking into account variations of atmospheric attenuation.
