MEASUREMENT MODELS OF ON-BOARD MAGNETOGRADIENT SYSTEMS

The purpose of this study is to develop an improved model of a magnetically gradient measuringsystem, which plays a key role in solving the problem of simultaneous estimation of the parameters of theEarth's magnetic field (carrier) and the parameters of the anomalous magnetic field. The relevance of thestudy is due to the need to optimize the process of differential magnetometry. Differential magnetometryallows you to extract useful information from a magnetic field without the need for time-consuming andlengthy detailed mapping of the area. This is achieved by estimating the parameters of the magnetic fieldgradient, which significantly increases the information content and efficiency of determining the locationof sources of magnetic anomalies. However, measurements of physical fields are significantly affected byvarious disturbances that may occur due to equipment and design errors, as well as due to their magneticproperties. These interferences distort the measurement results and reduce the accuracy of determiningthe magnetic field parameters. In this regard, the development of a model that takes into account the effectsof interference and compensates for their effects is an extremely important task. The proposed modelof a magnetically gradient measuring system will take into account the effects of interference and compensatefor 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 carrierfield and the constants included in the measurement model. This will increase the efficiency of differentialmagnetometry and make it more applicable in various fields. In particular, the improved magneticallygradient 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 allowyou to more accurately determine the boundaries of various geological structures, which is important forthe search for minerals. In the conditions of clearing the liberated territories of hidden objects left by theenemy, 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 developmentof an improved model of a magnetically gradient measuring system has a wide range of potentialapplications and is an important step in the development of differential magnetometry technologies
