AIR-TO-UNDERSEA COMMUNICATION WITH ELECTRIC DIPOLES
NEW MEXICO UNIV ALBUQUERQUE ENGINEERING EXPERIMENT STATION
Pagination or Media Count:
The ranges of various parameters involved in airto-undersea communication at 10 to 10 to the 5th power cps are briefly discussed. Sommerfelds integrals for the pi components in the two media ARE PRESENTED AND ARE SOLVED FOR THE QUASI-NEAR RANGE, SUBJECT TO CERTAIN MILD RESTRICTIONS. This is accomplished by defining two auxiliary integrals, asymptotic series expansions for which are made available by extending the work of Banos and Wesley. The solution for pi leads to the derivation of electromagnetic field components. It is found that, from field strength considerations alone, the best inter-communication scheme consists of a vertical electrical dipole in air with a horizontal electric dipole in the sea. Simple calculations for estimating the satisfactory communication range are included. Author
