The document discusses the applications and advantages of ultra-wideband (UWB) technology, highlighting its utility in low-power radar pulses for distance and velocity measurements, along with detection and imaging through barriers. It details the use of UWB in sensor networks for security purposes and provides examples of UWB imaging systems capable of high-resolution scans through concrete. Additionally, it mentions UWB RFID tags that are passive, cost-effective, and capable of long-range identification.

2. What makes UWB useful ?
 A very low power “radar”
pulse.
Penetrates and reflects
Distance & velocity
measurements
Detection & imaging through
barriers
Robust communication
RFID tagging

3. Following the WTC attack, radar pulse or Ultra-wideband
(UWB) search sensors were quickly deployed

6. UWB Imaging
The HERMES system can provide
high resolution, high speed, 100%
coverage for lane inspections
• Full 3D reconstruction algorithms
• Penetration through 16” concrete
The Radar Camera can electronically scan
through walls at video frame rates
• Electronically beam steered array
• Advanced reconstruction algorithms
• 15’-25’ range
• On the fly calculations

7. LLNL UWB RFID Tags – Are you here and where are you?
 LLNL’s RFID - passive and long range
(10 to 20 meters)
 Remotely powered
 Individual ID – store information
 Nano-watts power requirement
 Size – about two postage stamps
 Cost < $1
