Russian radar to search for people under the rubble at the site tested Emergencies

Special radar to search for people under the rubble has been tested on the range of MES in suburban Noginsk. The device is capable of finding people even under the multimeter heaps of concrete structures and can be used in rescue operations after the earthquake, and for the detection of miners after a collapse of rock or snowboarders, covered with avalanche.

Domestic Rescue Radar radar during testing compared with three similar devices. He has successfully coped with all the tasks and was able to detect people at four different sites, including bunkers and behind a pile of rubble concrete slabs.
"We compared a variety of devices that exist at the moment. It is our radar found the movement of people at all four sites, "- told reporters on the results of tests of the general director of the company" Life Sensor "that created the device, Gajrat Ikramov.

According to him, the unit distributes radio waves that detect movement — be it human movement or just slight variations of his chest when breathing.
"If we talk about finding the open space, the device is able to capture a person’s breath, that is, to capture variations of his chest at a distance of 50-70 meters. Naturally, in the rubble that distance becomes smaller, usually 5-10 meters ", — added Ikramov.

The device can be used not only to search for people trapped under the rubble after the earthquake, but in the course of the rescue operation at the mine site or avalanches.
"If we define a person’s movement in real time, to detect the breathing we need 15-30 seconds," — said the creator of the device.

Radar is able to provide information about the distance to the object of the search, as well as the frequency and amplitude of the human breathing. Based on these data, the rescuers can judge where and in what condition is the victim. In addition, said Ikramov, the frequency of breathing can be seen that under the rubble is just a person, not an animal.

The Russian unit is easy to handle. It is only one button: on and off. The search process itself is automated: the device put on the dam, under which a person may be a survivor, and begin to "scan" the ground. These are displayed on the computer screen, and transmit them to the radar can be a laptop as by cable and wirelessly.

Radar distinguished from foreign developments compactness and light weight. For example, the American counterpart weighs about 11 pounds, and wearing it to two people. Weight Rescue Radar — only 6 pounds, and you can carry it with one hand. In this case, it is protected from impact and moisture.

According Ikramova, the unit has limitations, but they are caused by the physical properties of materials, by which it may be affected. The main obstacles — water and iron, which do not pass radio waves. Wet soil or iron sheet narrow range of the radar.

Make a unique radar in Nizhny Novgorod, and the main market of the device — Japan and Southeast Asia. According Ikramova, Rescue Radar instrument is more than 50% of the market of radio wave Rescue Technology of Japan. About 20 devices Rescue Radar can be used by rescuers in the aftermath of the recent earthquake and tsunami in Japan, he said.

In 2009, the development has been awarded the Russian Emergency Situations Ministry at the "Integrated Security". However, Russian rescuers have not purchased any of the radar. However, Ikramov expects that the results of the test device is put into service MOE, and very soon it will be able to apply domestic rescuers.
