ABSTRACT:
The present invention relates generally to determination and display of vulnerability of marine vessels to mine threats.
BACKGROUND OF THE INVENTION
Currently, the vulnerability of Naval combatant sea vessels to sea mines is computed off-line, utilizing a disparate collection of data derived from different mine models, techniques and locations. Vulnerability estimates so obtained range from rule-of-thumb calculations to computer simulated ship-mine interactions. Influence data models currently utilized often are of a general or “class” nature and do not reflect the states or conditions of individual ships. Thus, the mine vulnerability information heretofore generated was of a widely varying quality and accuracy not readily available to Naval combatant commanding officers or fleet tacticians and strategists. It is therefore an important object of the present invention to more readily provide detailed and accurate information on board a marine vessel about its vulnerability to a wide variety of mine threats.
SUMMARY OF THE INVENTION
In accordance with the present invention, sea mine vulnerability data is calibrated and displayed on board a host ship by use of magnetic, electric, acoustic and other influencing signatures that are periodically updated by recalibration of their influence model parameters from sampled sensor measurements performed at a magnetic silencing facility. Such influencing signature models are utilized and interrelated with models of different world-wide sea mines and the current states and conditions of the host ship to provide calibrations which correspond to actuation surface onsets on the different mine models for a most accurate and readily available on-board display of sea mine vulnerability information.
