| 摘要 | An underwater weapons system having an encapsulated torpedo and an anchor assembly which may be planted in the water by a submarine, aircraft, or surface ship. Shortly after water-entry the anchor separates, leaving the encapsulated torpedo vertically moored at a predetermined depth. Detection equipment on the casing listens passively for a target, and upon target detection, an active transducer is activated to classify the potential target. Upon classification, the casing opens, releasing and activating a homing torpedo having self-contained target-seeking capabilities. | ||||||
| 权利要求 | 1. A torpedo-mine system capable of detecting and classifying an underwater target and releasing a torpedo to home in on the target comprising: a homing toRpedo; a sealed and openable casing encapsulating said torpedo; an anchor assembly adapted to moor said casing at a predetermined depth; an acoustic detection system independent of said torpedo provided in said casing for detecting signals from a potential underwater target; a signal processor system independent of said torpedo providing in said casing and responsive to said acoustic detection system adapted to classify a signal as a potential underwater target and to release said torpedo; and means responsive to said signal processor system for opening said casing to release said torpedo. 2. The torpedo-mine system of claim 1 further comprising a safing and arming mechanism including an arming device and a delay timing device responsive to said arming device, whereby upon lapse of a predetermined time after deployment said timing device turns on an independent power supply to activate the acoustic detection and signal processor systems. 3. The torpedo-mine system of claim 2 wherein said acoustic detection system comprises: a passive omnidirectional transducer activated after system deployment to listen for and determine a potential target signal and an active transducer responsive to said passive transducer adapted to emit and receive sonar signals in detecting a potential target. 4. The torpedo-mine system of claim 3 wherein said active transducer has a beamed transmission and reception pattern to discriminate against surface targets and concentrate on submerged targets. 5. The torpedo-mine system of claim 4 wherein said signal processor system includes signal logic control means to regulate the processing of signals from said passive and said active transducers. 6. The torpedo-mine system of claim 5 wherein said signal processor system further includes signal evaluation means responsive to said passive transducer to filter out random environmental noise and to activate said active transducer only when the detected signal is a possible potential target. 7. The torpedo-mine system of claim 6 wherein said signal processor system further comprises: a frequency band filter for attenuating signals from random environmental and surface noise signals and not attenuating signals from man-made submerged objects. 8. The torpedo-mine system of claim 7 wherein said signal processor system further comprises: a range and size gate for passing signals representing a target within the acquisition range of said torpedo. 9. The torpedo-mine system of claim 8 wherein said anchor assembly comprises: an anchor releasably attached to said casing, a line connected to said anchor and said casing, said line adapted to be stored in said casing and to be controllably released therefrom; and control means for releasing said line in sequential increments to moor said casing at a predetermined depth from the water surface. 10. The torpedo-mine system of claim 9 wherein said control means for paying out cable comprises: a plurality of hydrostatically actuated devices preset to operate in stepped increments of water depth. 11. The torpedo-mine system of claim 10 wherein said anchor line is a fine monofilament high-strength line. |
