DHS has awarded IAI a new contract to develop Scalable and Reliable RF sensing for Long-Duration Personnel Tracking

Recently, the U.S. Government Accountability Office reported that less than 1 percent of the 4,000-mile border between the U.S. and Canada is under the operational control of U.S. Border Patrol. Solutions that address this must detect, localize and track people in wooded terrain using mesh networks comprised of low power, covert, RF sensors based on standard, inexpensive commercial off the shelf (COTS) products used widely in wireless data networks. To address this, IAI has been awarded a contract entitled “ARGUS: Scalable and Reliable RF sensing for Long-Duration Personnel Tracking.” A novel mesh networked RF sensor will be developed based on IAI’s current and proven RF perimeter monitoring ARGUS system. ARGUS was developed by IAI and is manufactured under license by HARRIS Corp. ARGUS uses Zigbee-based COTS radios to establish radio links of length of about 50-100 m between nodes. Intruders near nodes are detected by changes in the RF channel due to motion and resulting changes in received signal strength. ARGUS scales to tens (tested) or hundreds (by analysis) of nodes, and all radio links can be used to detect intruders. ARGUS is a mature, well-tested technology, and will be adapted to meet the specific challenges in the DHS border application. First, sophisticated algorithms will be developed to reduce the Probability of False Alarm (PFA) in densely wooded environments. The ability of ARGUS measurements on different RF channels, bi-directional measurements and Time Of Flight measurements to provide independent information to reduce PFA will also be investigated. Secondly, use of node sleeping, low power detection algorithms, and efficient components will increase battery life. Lastly, economies of scale and eliminating unnecessary features will be used to decrease system cost
