Claim 1
Independent Claim
161 words
A METHOD OF DETECTING AND TRACKING AN OBJECT IN A WATER AREA BY A MOBILE STATION COMPRISING THE STEPS: OF MOVING THE MOBILE STATION OVER THE WATER AREA ON A SELECTED AZIMUTH, OF DISPATCHING A MULTI-BEAM DIRECTIONAL SONOBUOY FROM THE MOBILE STATION INTO THE WATER AREA, OF DISPATCHING A REPEATING EXPLOSIVE CHARGE FROM THE MOBILE STATION INTO THE WATER AREA NEAR THE MULTI-BEAM DIRECTIONAL SONOBUOY, OF DETERMINING A SECTOR LOCATION OF THE OBJECT WITH SAID MULTI-BEAM DIRECTIONAL SONOBUOY FROM A FIRST PRESSURE PULSE GENERATED BY SAID CHARGE, OF DISPATCHING AN OMNIDIRECTIONAL SONOBUOY FROM THE MOBILE STATION IN THE WATER AREA ON SAID AZIMUTH AT A DISTANCE WITHIN CONTACT RANGE FROM THE MULTI-BEAM DIRECTIONAL SONOBUOY, OF DETERMINING THE PRECISE POSITION OF THE OBJECT WITH BOTH OF SAID SONOBUOYS FROM A SECOND PRESSURE PULSE GENERATED BY SAID CHARGE, AND OF MOVING THE MOBILE STATION ON A COURSE APPROACHING THE OBJECT; WHEREBY THE MOBILE STATION QUICKLY ARRIVES AT THE PRECISE LOCATION OF THE OBJECT.
