A NOTE ON THE DETECTION OF UNDERSEA CRAFT BY MEANS OF LOW FREQUENCY RADIATION FROM AIRCRAFT
Keyword(s):
A semiquantitative examination is made of the chief factors affecting both the transmission of low frequency radiation from an aircraft to a submarine and the return of this energy to the aircraft by scattering. A general expression is derived for the returning field strength and graphs are shown for a representative set of conditions. It is indicated that, even under the most favourable conditions, the amount of energy returned is below the level of detectability, if the submarine is submerged more than 10 ft. However, it is also pointed out that communication between a shore station and an undersea craft should be feasible under certain conditions.
