  Abstract ▼

  The purpose of this study is to develop an improved model of a magnetically gradient measuring
  system, which plays a key role in solving the problem of simultaneous estimation of the parameters of the
  Earth's magnetic field (carrier) and the parameters of the anomalous magnetic field. The relevance of the
  study is due to the need to optimize the process of differential magnetometry. Differential magnetometry
  allows you to extract useful information from a magnetic field without the need for time-consuming and
  lengthy detailed mapping of the area. This is achieved by estimating the parameters of the magnetic field
  gradient, which significantly increases the information content and efficiency of determining the location
  of sources of magnetic anomalies. However, measurements of physical fields are significantly affected by
  various disturbances that may occur due to equipment and design errors, as well as due to their magnetic
  properties. These interferences distort the measurement results and reduce the accuracy of determining
  the magnetic field parameters. In this regard, the development of a model that takes into account the effects
  of interference and compensates for their effects is an extremely important task. The proposed model
  of a magnetically gradient measuring system will take into account the effects of interference and compensate
  for their effects, which will significantly improve the accuracy of estimating magnetic field parameters.
  In addition, the model will help solve the problem of jointly estimating the parameters of the carrier
  field and the constants included in the measurement model. This will increase the efficiency of differential
  magnetometry and make it more applicable in various fields. In particular, the improved magnetically
  gradient measuring system will be useful in geophysical mapping, mineral prospecting, environmental monitoring, as well as in specific combat conditions. For example, in geophysical mapping, it will allow
  you to more accurately determine the boundaries of various geological structures, which is important for
  the search for minerals. In the conditions of clearing the liberated territories of hidden objects left by the
  enemy, such as mines or underground structures, the system will help to identify them quickly and accurately,
  which will significantly increase the safety of military personnel and civilians. Thus, the development
  of an improved model of a magnetically gradient measuring system has a wide range of potential
  applications and is an important step in the development of differential magnetometry technologies
