Регистрация спектра интенсивности электромагнитного поля I(ν) производится
высокочувствительным многоцелевым сканером нового поколения «DSF» (авторская
разработка Богданова Ю.А. и Прокопенко С.И.), аттестованным в ННЦ «Институт
Метрологии» г. Харьков [1].
Сканер характеризуется высокой чувствительностью (не более 1*10-6А/м);
быстродействием (10 изм/сек); широким диапазоном рабочих частот (от 1 кГц до 50 кГц по
уровню -3dB); широким диапазоном рабочих температур (от -30°С до +60°С); малыми
габаритами электронных блоков (100х100х70мм и 160х100х65мм); небольшим весом (не
более 3 кг).
Блок антенн размещается с помощью специальных креплений на судне. Навигационный
модуль сканера базируется на использовании спутникового навигационного приёмника.
Приемник позволяет вести одновременную работу со спутниками двух созвездий: «GPS» и
«ГЛОНАСС», что гарантирует определение координат точек измерения в любом районе
земного шара с точность позиционирования не хуже 2.5 м CEP и не хуже 5.0 м SEP.
Удаленный контроль регистрируемых данных в онлайн-режиме обеспечивается встроенным
трехдиапазонным GSM/GPRS модулем. Регистрируемые в точке измерения параметры
электромагнитного поля передаются по каналу GPRS на удаленный FTP-сервер, что дает
возможность оперативно контролировать качество поступающей информации.
Основные решаемые задачи: поиск зон геологических глубинных тектонических
нарушений, картирование нефтегазоносных и перспективных структур, поиск подземных и
термальных вод, удаленный контроль опасных геодинамических процессов в земной коре.
Геофизическая съёмка выполняется на воздушном, морском и автомобильном
транспорте, а также в пешеходном варианте по системе параллельно-перпендикулярных
маршрутов согласно заданному масштабу съёмки. Направление рабочих профилей: запад-
восток и юг-север. Средняя высота движения 100 м, аэросъёмка выполняется с генеральным
обтеканием рельефа. Средняя скорость на маршруте составляет 100 км/час.
С 2013г. по настоящее время Сканер «DSF» применяется в геофизических экспедициях
во многих странах таких как: Украина, Россия, Болгария, Китай, Канада, США, Иордания,
Судан, Египет, Малайзия, Индонезия и др.

APPLICATION OF THE PASSIVE GEOPHYSICAL SCANNER "DSF" FOR RESEARCH
OF THE DEEP STRUCTURE OF THE EARTH
Prokopenko Serhiy
(LLC "MAK SPETS AVIATION INDUSTRY" Kharki ,geopolariton@gmail.com)
Application area DSF is extended to work in two global positioning systems "GPS" and
"GLONASS" and in the on-line transfer of data to the Ftp-server. High reliability of information is
provided.
... Structurally, the scanner consists of two units -receiving antennas unit and signal processing unit. Block enclosures have a certain degree of environmental protection IP64 (Prokopenko, 2017). The receiving antennas unit contains three antennas, the radiation pattern of which are located in three mutually perpendicular planes and an antenna amplifier with a symmetrical output, which makes it possible to reduce induced electrical interference during signal transmission through the communication line. ...

The hardware part of the GPTS platform is represented by a passive remote geophysical scanner "DSF16C" and the software products "Points Remover", "DSF16", "LSpectr", "MODE" for data processing and interpretation. The platform provides profiling of speed (material) sections and their geometric representation. The field of application is the study of the Earth's deep structure. The method of estimating of the dynamic states of rock massifs allows estimating the resource of deposits at large depths and signs of replenishment of reserves even at the stage of selection of promising areas, as well as in previously identified deposits, until signs of their activity decrease appear to prevent reduction of their oil recovery. A fundamentally new data processing algorithm simultaneously evaluates all geodynamic processes (stress-strain state, state of rupture disorders in all complexes and a complex system of their interactions), taking into account the activity indicators of the Earth's natural electromagnetic field. It is possible to install the scanner on any mobile carrier: UAV, ship, aircraft, car. Stress-strain state of rocks, energy of elastic natural vibration of the Earth's core, geopolariton tomography technology (GPTS).

An innovative technology for monitoring fire preparation zones in sections and dumps is presented. The technology uses a low-frequency range (1-100 kHz) aerial survey of Earth's natural electromagnetic radiation. The survey is performed with a geopolariton tomography equipment mounted on a multi-rotor unmanned aerial vehicle (UAV). A hardware and software complex "GPTS" is designed to identify moistened rock massifs (RM), zones of increased mountain pressure, to monitor the formation and development of coal self-heating centers. It allows taking action before the coal self-heating process begins to switch to the fire stage. The mobility and efficiency of the complex deployment allow controlling large areas. The visual display facilities of active rock disturbances and non-contact measurement of density characteristics of the RM significantly simplifies the control of mining sites. The experience of successful experimental and methodological work in the mountains of the Yunnan Eastern Plateau, a coal mine in the Qilin District Qujing region is presented.

Passive radar remote sensing of the centers of destruction of natural-technical systems in a wide range of wavelengths is a scientific and technical direction, which allows to obtain qualitatively new information about the stress-strain state of objects immersed in the geological environment. Schemes and principles for the analysis of the interaction of engineering structures with the natural geological environment using airborne geophysical tomography are developed. Mapping and diagnostics of the structure of disturbing influences - risk sources that complicate the operation of real estate and reduce the time between failures. The unevenness of the impacting factors on the part of the rock masses at the locations of linear structures and high-risk structures was discovered by the included observation method. A specification has been developed for a unified air complex for remote sensing of complex structures and city monitoring in order to timely identify life-threatening incidents using manned and unmanned aircraft and working models of hardware and software implementation of the complex units. On the basis of the obtained data, maps and vertical geological sections of stress-strain activity were constructed at various scales and the tendency for the development of hazardous natural ones is calculated and technogenic processes.

A search was made for suprasalt and subsalt formations of oil. Received models of the deep structure (speed and geological) to a depth of 60 km. Geopolariton survey of the Earth was used to build high-speed sections of geological profiles. The studies were conducted as part of a joint agreement with the company “Kazakhstankaspiyshelf” JSC.
