Submarine Communications

  title={Submarine Communications},
  author={H. Singh},
Submarines operating i]1 deep water are virtually cut off from the outer world. It becomes very important and essential to convey survivable and critical informations to the submarine during the time it operates under water. Conventional means of radio communication do not serve any useful purpose as the higher frequencies get attenuated very sharply in sea water. At VLF band, which is presently being used by most of the world Navies, signal can penetrate only upto 8-10 m of depth. This depth… Expand

This work demonstrates a lead zirconate titanate transmitter that is6000 times more efficient than a comparably sized electrical antenna and capable of bit rates up to 60 bit/s. Expand


Nuclear Hardened Radio Communication to Submarine: A Review
In the event of nuclear war, the availability of a reliable communication facility would be of absolutely vital importance to any nation. Further to pass on certain emergency signals to a submarineExpand
Radio communication in the sea
Because of the electromagnetic properties of seawater, very-low-frequency communication systems are used, Surface-to-submarine, submarine-to-surface, and submarine-to-submarine propagation, as wellExpand
Development of a Trailing-Wire E-Field Submarine Antenna for Extremely Low Frequency (ELF) Reception
A rationale is developed for the present trailing-wire receiving antenna system based on the history and specific Sanguine work, and design details, construction techniques, and testing methods are discussed. Expand
Radiation and reception with buried and submerged antennas
The paper is intended as a link between the abstruse boundary value problem solutions and the systems engineer. A brief bibliographic review of the boundary problem is given, followed by a discussionExpand

The early research and tests provided confirmation of the theory that a vertically polarized E -field propagates through the earth ionosphere cavity at ELF with a slight forward tilt which allows it to enter the sea water and then penetrate to considerable depths. Expand
