Tarantula tunnel-sensor system deployed on U.S., Gaza borders

TEL AVIV — An underground sensor designed to detect tunnel construction and operation is undergoing continued testing.   

ISpider Technologies Security has produced and delivered sensors meant to detect and track underground and above-ground activity. Executives said the Israeli military as well as the U.S. government have been testing the systems for underground and above-ground movement, including people and vehicles.

Executives said the sensor system, called Tarantula, has been deployed along the U.S. border as well as the Israeli border with the Gaza Strip. They said SpiderTech, based in Netanya, was also conducting field trials of its sensor network in Europe and South America.

"The most recent tests in the U.S. involve tunnel detection," SpiderTech marketing director Elkana Pressler said. "The demonstrations have shown that the SpiderTech sensor can accurately identify people moving underground even with intense surface noise, like car and truck traffic."

Tarantula was said to comprise a network of seismic sensors based on signal processing technology that could detect the approach of people and vehicles above ground as well as underground activity. The network of up to 200 sensors was designed to operate via a personal computer with command and control system software.

In prototype testing in Israel and the United States, Tarantula, said to have a false alarm rate of below 10 percent, detected people at a distance of 30 meters and light vehicles at 100 meters. Executives said the ranges of the three-dimensional sensors — each measuring 140x105 mm and with an accuracy of up to five meters — were about twice that of existing sensor technology systems.

"The sensors have a very low rate of false alarms, thus being extremely difficult to bypass and enhance any existing perimeter security solution," SpiderTech said on Sept. 29.

SpiderTech has signed an agreement with Israel's Rada Electronic Industries for the marketing of Tarantula in an effort that could result in contracts in 2010. Executives said Rada would focus on Western governments and militaries, particularly the United States. The system, which does not require a line of sight with targets, has already been tested by the U.S. Homeland Security Department in cooperation with the Washington-based firm SAIC.

"We are currently focused on the high-end government market segment where our solution is urgently needed," Pressler said. "We also intend to expand our offering and introduce a commercial product line, tailored for home protection."
