Undersea Detection of Various Signals

Abstract

Tradeoffs involved in the undersea detection of static and time- varying signals are examined and the quantitative results are discussed in this report. Static electric and magnetic fields, radioactive fields, chemical systems, extremely-low-frequency (ELF) electromagnetic radiation, light, and acoustics were studied, and the results were tabulated in chart form. For time- varying fields, underwater light exhibits inferior range and ELF exhibits inferior bandwidth when compared with acoustics. Ranges from approximately 3 to 14 km are achievable for chemical and ELF sources, respectively, when they are used as static markers.
