ABOARD MAGNETOMETRIC SYSTEM FOR DETERMINATION OF THE LOCATION OF A SUBMARINE Russian patent published in 2006 - IPC G01V3/08 

FIELD: the invention refers to the field of aboard magnetometric means of detection and determination of anomalies and sunk ships.

SUBSTANCE: the system has a magnetometer and a filter connected in series and also a transformer voltage-code, a sensor of the speed of a carrier and an arrangement of evaluation of weighting coefficients of the magnetometric signal of a submarine. The output of the sensor of the speed of a carrier is switched to the first input of the transformer voltage-code. Besides the system has the second magnetometer, the second filter, a commutator, a memory block and a control block, whose outputs are connected with controlling inputs of the commutator and the memory block. At that the output of the second magnetometer is connected with the input of the second filter. The outputs of both filters are joined through the commutator to the second input of the transformer voltage-code whose output is switched to the input of the memory block. The output of the memory block is connected with the input of the arrangement of evaluation of weighting coefficients of the magnetometric signal of a submarine.

EFFECT: increases accuracy of determination of the coordinates of a submarine and its classification in accordance with the value of a magnetic moment.
