Opis:: In marine environment there are different types of objects, such as ships or naval mines, which should be located and identified. One of the location methods is based on the electric potential distribution measurement [1, 2], The object with an insulating or conductive casing, placed in an electric field, causes some field perturbations. For the purpose of the object location the dimensions of the area, where it is possible to determine electric field perturbations by measurement, are important. In this way one can pre-determine the extent of the system for locating and identifying objects placed in the seawater. This paper presents an analytical approach to the perturbation analysis of electric field distribution caused by a sphere and an ellipsoid placed in a uniform electric field. The distance, beyond which the uniform electric perturbations can be neglected, is determined.

Tematy:: ferromagnetic object
magnetic field
ferromagnetic shell
Opis:: A ferromagnetic object, located in the Earth’s magnetic field, changes its distribution. Through measuring such disturbances, one can locate the object and destroy it. To conceal the object, a special winding is placed inside its ferromagnetic shell, and its task is to eliminate the disturbances in the distribution of the Earth’s magnetic field. A thin walled elliptical shell, made of ferromagnetic material, is examined as the object model. There are coils, placed inside the shell, and their task is to generate a magnetic field, which is eliminating the effect, the shell is making on the distribution of the Earth’s magnetic field in the surrounding area. Such a procedure is called magnetic masking and the winding used for this purpose is called the masking winding. The possibility of building the masking windings for the ferromagnetic elliptical shell, situated in a transverse magnetic field respectively to its major axis, is also examined. The solution of Maxwell’s equations, which are describing the magnetic field distribution caused by the ferromagnetic shell presence in the Earth’s magnetic field, is found. Furthermore, the ability of selecting coils, which are eliminating the perturbations of the magnetic field outside the shell completely, is proven.

Tematy:: electric field
object location

Opis:: There are electrochemical processes occurring on a metal object surface in seawater. As the result of these processes, one can observe an electric field in the object vicinity. The paper presents the method and measurement system that allows to locate the detected object and to identify parameters of its simplified model in form of a current dipole. The identify method is based on the matrix norm minimization. The matrix contains results of measurements and parameters of the object in request taken as the current dipole. The results of simulation and experimental detection of sea mines are given. The research results confirmed the effectiveness of the developed method.
