Recognizing the performance and ability of advanced remote sensing technologies is one of the essential necessities to hide subsurface structures and facilities. One of these detection technologies that has used in Ionospheric Powerful Electromagnetic Heater Systems, is HAARP. This system uses electromagnetic fields signals in the frequency range 3 to 10 MHz. HAARP emits waves into one of the layers of the ionosphere and then warm the desired area. This leads to emit very low frequency waves in the range of VLF and ELF. The main objective of this research is to analyze the exploratory capabilities of the HAARP system remote sensing in detecting subsurface targets. In the case of the accuracy of remote sensing capabilities and the ability to identify subsurface targets by HAARP, it can be concluded that this system is a very serious threat to identifying major subsurface targets in the country and poses a serious challenge to inactive passive actions. Therefore, it is necessary to carry out strategic, operational and tactical planning to deal with this serious threat. However, in case of inaccuracy of this capability, it will resolve the uncertainties and anxieties of the minds of the commanders and officials of the country, especially in the field of passive defense of the country.The only research published in the country by the men of Mardani and Razavi Nejad (Mardani et al., 2011), published as a two-volume book, address the issue of the ability of the HAARP to make climate change. But in the area of detecting subsurface targets, no published scientific research has ever been presented.
Materials and Methods
This research utilizes a combination of multiple data analysis based on analyzing the data collected from scientific and theoretical sources, official and authoritative reports the results of experiments performed and finally the main research question has been answered by taking the viewpoints of experts and scholars of research statistical population. The type of research is applicable and the research method is descriptive-analytical and case-based. In this research, the required information is obtained through the search of Internet resources, authoritative scientific documents, books, internal and external publications, dissertations and researches carried out on the topic, opinions of experts based on interview and used to the Delphi scientific method in the field.The statistical population of this research includes scholars, academic experts and research centers in the fields of remote sensing, Ionospheric Powerful Electromagnetic Heater Systems and high-power radars in the country. The sample population of the study was 32 experts who were purposefully selected from the statistical population of the study.
Results & Discussion
The main objective of this research is to analyze the capability of remote sensing of high-power electromagnetic heat sink systems (HAARP) in identifying subsurface targets. The HAARP system uses electromagnetic fields with signals in the frequency range of 3 to 10 MHz, and can operate in the same way as the frequency domain electromagnetic geophysics. The Harp system, as an ionospheric heater, modifies the ionospheric heating using polar electrodes of the desired frequency waves and uses it as a source of waves for remote sensing and identifying subsurface targets.
The results of this research show that the electromagnetic ionospheric heater power systems have remote sensing capabilities and can recognize subsurface targets. Accordingly, in this research, some solutions for passive defense against Remote sensing threats of HAARP system is provided. In general, HAARP provides the capability of a remote sensing system and subsurface radiography globally, and is a good option for underground exploration with the CSAMT approach. In this research, using the combined method of analyzing multiple data based on the description and analysis of data collected from scientific and theoretical sources, official and authoritative reports, examining the results of empirical experiments, and finally obtaining expert opinions and owner the statistical community of the field survey has responded to the main question of the research.
The results of this study show that high-power electromagnetic immune systems (HAARP), has remote sensing and the ability to identify subsurface targets. Accordingly, these systems are considered to be a serious threat to identify sub-targets, and therefore, in-depth research has suggested inaccessible defense strategies against this threat .Also, the results of the research showed that if the equipment is buried in a high conductivity ground, they cannot be detected by the HAARP VLF waveforms. If the waves of the HAARP system are of the type of ELF waves used in the CSAMT method, it can be used to prevent detection in addition to conductive ground, to deploy structures at depths of more than 150 meters.
