PROCESS ENERGY

Safety and Security are two critical issues for the process / energy industry. Ensuring either requires knowledge of the precise location of all people and assets, whether they are supposed to be on site, and especially if they are not. Time Domain's technology offers the ability to find people and objects equipped with tags in real time, and even to detect and track intruders without tags. Additionally, our UWB solutions provide robust wireless communications for such applications as sensor telemetry, even in the extremely harsh RF conditions of a process facility. Applications include:

  • Precise tracking systems for personnel safety and awareness
  • Intruder detection and tracking systems
  • Equipment and asset tracking systems for efficiency and safety
  • Wireless communications systems for robust, location based sensor telemetry

CRITICAL INFRASTRUCTURE

From nuclear power plants to cattle feed pens, from pipelines to borders, and from shipyards to airports, the list of infrastructure critical to the Nation's economy and security is as diverse as many of the facilities are vulnerable. Traditional methods of infrastructure security can often be very costly and time consuming to install, not feasible due to geographical constraints, or sometimes just inadequate for the task. Time Domain's technology can augment traditional techniques by supporting:

  • Wireless perimeter security fences for real time, low false alarm rate intruder detection
  • Quick-install perimeter security fences for cost-effective protection, particularly in temporary circumstances
  • Real time intruder tracking systems for pinpoint interdiction
  • Equipment and personnel tracking for monitoring and protection

PulsON in Practice: Radar Fence detects, classifies and tracks intruders in the open and in foliage

Time Domain is engaged in a development project with Applied Physical Sciences to produce a virtual Radar Fence. The Fence uses P400 platforms to form a multi-mode radar (mono-, bi-, multi-static) fused with a UWB communications/network backbone. The Fence consists of individual Fence Posts that are 10 feet tall and contain P400 platforms spaced to provide multiple radar look angles. The UWB Fence Posts are arranged in two offset rows of poles separated by 60 meters. When operating in foliage the separation distance is reduced to 25 meters. The system detects targets as they move through the area and produces radar images of the targets. The system then analyzes the images and computes underlying statistics. These statistics allow the target to be classified as human or quadruped. Small creatures such as birds, rodents and other small animals are ignored. The target classification, position and direction of movement are then reported to a command center which can then cue a camera or send a response team.
