| 摘要 |
The invention relates to a method and a device for sweeping marine mines having a magnetic sensor by at least three electrodes (10, 11, 13) spaced apart and tractored by a vessel (12) and behind each other, said electrodes being provided with electric current from said vessel (12) for generating a magnetic field in the water surrounding said electrodes (10, 11, 13), each of said electrodes (10, 11, 13) separately being provided with electric current of individually adjustable strength. The invention is characterised by varying in time the current strength of the current fed to said electrodes between positive and negative limits with intermediate zero passages to separate the time for zero passage of the current to at least one of said electrodes (10, 11, 13) from the time for zero passage of the current to the rest of said electrodes (10, 11, 13). |
