  • US Patent:
    40204502, Apr 26, 1977
  • Filed:
    Jan 5, 1976
  • Appl. No.:
  • Inventors:
    Serge Kostrukoff - San Diego CA
  • Assignee:
    The United States of America as represented by the Secretary of the Navy - Washington DC
  • International Classification:
    G01V 118
    G01V 138
  • US Classification:
    340 155GC
  • Abstract:
    A hydrophone and preamplifier are coupled to receive signals representative f impinging acoustic energy. At the other end of a long length of two conductor coaxial cable, a receiver section provides representative voltage signals for following processing circuitry. DC power is fed to the preamp section along the single cable which also transmits the information current signals back to the receiver. The receiver section is designed to present a very low input impedance to enable the swamping out of the capacitive reactance introduced by the long cable. This allows the use of a long coaxial towing cable without introducing any appreciable frequency response degradation. Suitable electronic interconnection ensures that the preamplifier output signal is not affected by the supply voltage back at the receiver section and moderate potential variations between the cable ends do not introduce spurious noise components.
