LDART: Laser Detection & Reciprocal TargetingA lightweight, easy-to-deploy technology for improved battlefield situation awarenessImplemented as a patch attached to a soldier or vehicleCombines capabilities provided by multiple systems into one small packageDetect if soldier/vehicle has been painted by laserAccurate location of source of laser (new capability)Friend-or-foe identificationReciprocal targeting (new capability)Functions are easily separableCan interface with existing systemsSituation awareness systems e.g., Objective Force Warrior displays and vehicle cockpit display systemsTarget designators

LDART: Laser Detection CapabilitiesDetect when soldier/vehicle has been painted by laserRange finderTarget designatorBeam riderSpotting BeamBattlefield illuminatorCan identify direction of laser sourceWithin 0.06 degrees (1m for source at 1km)Can estimate distance of laser sourceAccuracy depends of distance of source and size of patch1m2 patch can estimate distance of target at 1km within 30mGreater accuracy for closer sourcesContinues to track direction and distance of source even as source and target move relative to each otherTarget DesignatorRange Finder

LDART: Hardware TechnologyHardware based on MEMS technology being developed by HoneywellSponsored by the DARPA/MTO STAB programThe LDART fabric consists of a large number of cellsCell size: 1 mm2 (~40,000 cells in 8inX8in area)Each cell consists ofA micro-lens (0.1mm diameter)Drives to move lens in x and y directionsDetector or laser under the lens at its optical axisCompute element to control cellCommunication links to neighboring cellsTop and Side View of a Single Cell
