Seismic Web and Tarantula

Special equipment in the service of the military



Modern war is characterized by high dynamic actions and extremely wide use of special operations forces. The task of timely detection and accurate classification of the enemy’s moving ground (underground) objects is among the priorities for the escort forces, while ensuring reliable security of the land borders. Today, the solution of this problem with a high degree of efficiency is no longer possible without the use of special equipment, including seismic sensors.

Power structures of many countries have been using special equipment for a long time. But so far, the task of detecting the presence of a moving object, determining the coordinates of the target, the direction and speed of its movement, and also, more importantly, its classification with a high degree of accuracy, has not been solved at the proper level. Only by solving these mini-problems can we talk about an effective system for detecting and issuing target designation to fire weapons or duty groups.

Israeli company Spider Technologies Security offered one of the most interesting solutions. This is the Tarantula perimeter protection system, the core of which is various seismic sensors and powerful computing devices that use special algorithms for processing received information and outputting elements of target movement, as well as generating target designation data for their fire weapons. Today, the system is being tested and has already aroused great interest of specialists from the Israeli Ministry of Defense and the US Department of Homeland Security. Information about this was recently made public in foreign specialized media.

As a means of detection, small-sized autonomous three-coordinate high-sensitivity seismosensors buried in the ground are used that can detect moving objects: personnel, enemy vehicles and armored vehicles, as well as establish the fact and nature of excavation work. Representatives of the company-developer say that the detection range of these sensors is twice the range of all devices of similar purpose present in the global market. According to the results of field trials, according to Spider Technologies Security, the range of confident detection of a person walking at ease - 30 meters, a passenger car - no less than 100, heavy vehicles or armored vehicles - at least 300 meters. It was possible to achieve high accuracy of target classification and determination of its coordinates with an error of no more than five meters.

The main unit of the detection loop of the Tarantula system is the SpiderTech Sensor (STS) seismic device, which is the know-how of an Israeli company. It is a cylinder 140 mm in height, 105 mm in diameter and 2,5 kg in mass, structurally consisting of three pairs of seismic sensors, which provide for notching the seismic oscillations of the target, as well as an integrated processor that processes the received signals and forms a three-coordinate target position. The devices are able to work in conditions of increased humidity, up to 100%, of humidity and do not lose their performance at temperatures ranging from -20 to + 80 ° C.

During testing, seismic devices were installed at a depth of 50 centimeters (this is the minimum depth - if necessary, can be installed at a greater depth), at a distance of 40 meters from each other, forming a kind of network or web controlled by a single computing center (combat post). Each such post is capable of controlling up to two hundred devices, while up to 200 similar mini-webs can be installed on a single control center, which will allow creating a seismic perimeter security system in which up to 40 thousands of seismic devices will be involved. The presence in each such device of its own mini-computer allows you to speed up the processing of information received at the combat post and avoid the "overload" of the data exchange line.

Tarantula tests are carried out in an environment as close as possible to combat, in different geographical and climatic conditions, in different types of soil. According to experts who are familiar with the results of individual stages of testing, the new system, while eliminating certain minor flaws, suggests the emergence of a fundamentally new class of perimeter security system with a very high practical potential.

In particular, according to representatives of the US Department of Homeland Security, this seismic web can provide tangible assistance in detecting work on the construction of underground tunnels on the border with the US (meaning the US-Mexico border) or in providing security for the perimeter in the protected areas of military bases and camps in combat areas.

From the statements of experts and officials it is clear that the Americans were especially impressed by the high sensitivity of seismic sensors developed by Israeli specialists, capable of detecting the slightest movement of people in underground tunnels within a given radius, as well as the ability of the system to distinguish between artificial (enemy) and natural (nature) origins .

Special algorithms allow you to automatically cut off, if necessary, some unwanted noise of artificial origin, such as noise located in the protected area of ​​the airport, highway or railway. The relatively low cost of the system - about 100 dollars per meter of the protected perimeter - makes Tarantula very attractive for military and border services, as well as for private military companies and security divisions of industrial corporations. Such a system would also be useful for Israel itself, which for many years already has a “headache” in the form of many kilometers of borders with Arab states - Egypt and Jordan, as well as with “rebel territories” - for example, Lebanon and the Gaza Strip.

The intellectualization of security systems is evident, while in Russia they continue to rely mainly on mass character: a large number of law enforcement officers carrying out typical patrols. But a similar, based on seismic sensors, the railroad bed guard system was developed several years ago and proposed to be put into service by specialists from the Research Institute of the Railway Forces of the Russian Armed Forces. The system includes small autonomous seismosensors installed along the railway tracks at a certain interval from each other and transmitting information either to the central control and monitoring station or to mobile or portable control stations. The slightest attempt to "dig up" the canvas and install a subversive charge there would immediately be displayed as an alarm on the attendant’s console and there would be no incidents with the Nevsky Express.

    Similar systems were used in the USSR back in the 70s. The truth is not on seismic sensors.
