Abstract
Способ определения стационарного геомагнитного поля при проведении морской магнитной съемки, заключающийся в одновременном измерении вариаций геомагнитного поля двумя или более магнитометрическими преобразователями, установленными на носителях, разнесенными на заданное расстояние вдоль направления движения носителей, в котором один магнитометрический преобразователь дополнительно разнесен по вертикали на расстояние 100-200 м от морской поверхности, с возможностью его перемещения вдоль направления движения первого магнитометрического преобразователя с последующим его перемещением поперек направления движения первого магнитометрического преобразователя со скоростью движения, превышающей скорость первого магнитометрического преобразователя по крайней мере на порядок, отличающийся тем, что дополнительно выявляют локальные аномалии геомагнитного поля в точках между смежными направлениями движения путем измерения значений глубин и их координат выполнения вычислений значений напряженности геомагнитного поля в точках между смежными направлениями движения носителей в соответствии с зависимостью: ! ! где КНН, KHZ, KZZ - ковариационные матрицы напряженности геомагнитного поля, напряженности магнитного поля и глубины, глубины акватории на съемочном галсе; ! |G| - вектор-столбец исходных данных; ! ! где N - число пунктов, расположенных на расстоянии, равном радиусу корреляции значений ; ! и - измеренные значения напряженности геомагнитного поля и глубины эхолотом вдоль съемочного галса в пункте i с координатой xi. A method for determining a stationary geomagnetic field during marine magnetic surveying, which consists in simultaneously measuring the variations of the geomagnetic field with two or more magnetometric transducers mounted on carriers spaced a predetermined distance along the direction of movement of the carriers, in which one magnetometric transducer is additionally spaced vertically by a distance of 100- 200 m from the sea surface, with the possibility of its movement along the direction of movement of the first magnetometric of the first transducer with its subsequent movement across the direction of motion of the first magnetometric transducer with a speed exceeding the speed of the first magnetometric transducer by at least an order of magnitude, characterized in that local anomalies of the geomagnetic field at the points between adjacent directions of motion are additionally detected by measuring the depths and their coordinates perform calculations of the values of the geomagnetic field at points between adjacent directions of motion but Itel according to the relationship: ! where KNN, KHZ, KZZ are the covariance matrices of the geomagnetic field strength, magnetic field strength and depth, the depth of the water area on the survey tack; ! | G | - a column vector of the source data; ! ! where N is the number of points located at a distance equal to the radius of the correlation of values; ! and - the measured values of the geomagnetic field strength and depth with an echo sounder along the survey tack at point i with the coordinate xi.
