Portable optical range tracking array
First Claim
1. A portable tracking array comprising:
- means for acquiring an acoustic signal, said acoustic signal acquisition means being encapsulated within a plastic material;
means for transmitting signals to and for receiving signals from said acoustic signal acquisition means, said signal transmitting means having an end encapsulated within a terminal coupling; and
a length of perforated material extending between said terminal coupling and said encapsulating plastic material to allow water entry and to substantially eliminate air cavities which interfere with acoustic performance.

Abstract
A portable tracking array to be used in a system for determining the tracknd/or the range of a target vehicle. The array includes a fiber optic hydrophone for acquiring acoustic signals from the target vehicle. The fiber optic hydrophone is encapsulated within a plastic material such as polyurethane. The array further includes a fiber optic cable for transmitting signals to and for receiving signals from the fiber optic hydrophone, which fiber optic cable has an end encapsulated within a termination coupling, and a length of perforated material extending between the terminal coupling and the plastic material encapsulating the fiber optic hydrophone to allow water entry and to substantially eliminate air cavities which interfere with acoustic performance.

13. A portable tracking system comprising:
-
at least one sensor package for sensing acoustic signals and for generating output signals representative of said sensed acoustic signals, each said sensor package having a first cable termination coupling at one end and a second cable termination coupling at a second end, each said sensor package further having a fiber optic hydrophone encapsulated within a plastic material and lengths of hose extending between said encapsulated fiber optic hydrophone and each of said cable termination couplings; means for processing said output signals to determine at least one of the track and the range of a target vehicle; and an optical fiber cable linking said processing means and said at least one sensor package, said optical fiber cable containing an optical fiber, said fiber cable being coupled to said first cable termination coupling and wherein said optical fiber protrudes from an end of said optical fiber cable and passes through said first cable termination coupling. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
