  • Low-power, wireless, netted sensors -- The Problems
    • Significant advances were accomplished in distributed processing of netted sensors, mote-based sensors were severely lacking:
      • Produced excessive false alarm rates
      • Provided low probability of detection,
      • Exhibited ineffective detection ranges (<10m)
      • RF range ~ 20-30m (on the ground); indicate netted mote period ~ 10m
    • Numerous systems issues included:
      • Random processor performance
      • Low battery life
      • Extremely difficult to maintain (no fabrication/design feasibility)
    • RF emissions that would jam, or interfere, with field operation.
    • Mote designs not consistent to that required by end-users, and could not be modified to accommodate such demands.
  • MLRmote Solution
    • Use of active optics (micro solid-state laser radar)
      • High Pd
      • Low FAR sensor (require target characterization to discern target types)
      • Significant operational range (100-1000m)
    • Address power use
      • Sensor X
      • Nearest-neighbor field processing to provide detection/trigger criteria
      • Solar recharging circuit (polysilicate solar array)
      • Coordinate with effective relay structure (SERI)

  • Effective sensor data exfiltration & commanding -- Problems
    • Scalability quickly overwhelmed relay technologies build to work with mote fields (throughput handling capability overwhelmed by message traffic)
    • Relay-to-relay communications were not considered and/or realized in mote-field environment (R2R allows for data/command transport sharing)
    • Adaptive exfiltration schemes not addressed, including use of worldwide communications architecture such as GSM, which provides multi-level security, broadcast (1-to-M) capability, redundancy (ref. AT&T)
    • In-field processing minimal (relay capability can support data processing and/or compression)
    • PULSENet compatible (OGC compliant)
  • Solution -- SERI Capability
    • Provided direct connectivity to in-field participants
      • GSM exfil directed to preplanned cell accounts -> Smartphone provided real-time health/status information
      • Worldwide support in place
      • Expandable using 1:M broadcast (supports R2R link)
    • Supports adaptability for L-band (previous exfil) and GSM
    • Allows for in-field processing expansion
    • Supported imager activity based on relay/field queuing

  • MLRmote & SERI : Summary
    • Based on success of 2241 netted mote field (DARPA NEST & ExANT programs) June 2006
    • Demonstrated large area coverage
      • Demo Sept 2007, Tampa (30-m)
      • Demo Oct 2007, Camp Peary (R > 109 m)
      • Demo Dec 2007, GEO-ISR DAY/Dahlgren (30-m)
    • Augmentation with PIRmotes (Sensor X) provides large area coverage at reduced cost
    • High-performance (SIRF3) GPS provides localization
    • RF capability provided by 2.4GHz/900MHz transceivers
      • Enhanced 900MHz range through DTI resonator
      • Use of relay-to-relay (SERI) capability
      • Reach-back includes SATCOM, GSM (SERI)
    • Use of sophisticated mote core (Sentilla Tmote) and SDK (JVM)
    • LRF (MLRmotes) improvements designed & planned
  • ARMMIC
  • ARMMIC Project Overview – Background
    • Advanced Micro-Mapping Integration Capability (ARMMIC) integrates emerging technologies to form next-generation geospatial information solutions for front-line , GPS-disadvantaged users
    • ARMMIC will develop and demonstrate integrated system solutions associated with the mapping of structures including:
      • ISR-based missions (structure mapping, building, tunnels, GPS-absent areas)
      • CNTPO-related missions (hidden compartment discovery)
      • Accurate, real-time, comprehensive, small-scale mapping (micro-mapping) capability
    • ARMMIC employs technologies investigated during previous TASC IRaD activities (MLR, SERI, PulseNET).
      • RFID positioning (RSSI) and identification
      • Autonomous ground vehicle adaptability
  • ARMMIC – Problems Addressed
    • Objectives associated with a military, civil, security -- a detailed “map” of a structure, or area-of-interest, especially those enclosed or underground, become the first order.
    • ARMMIC provides a GPS capability where GPS is non-existent.
      • Military applications -- pursuit of persistent intelligence, surveillance and reconnaissance (ISR) require location of targets detected and/or tracked.
      • Mine operators -- required constant communication and maintain constant position data on all personnel available to those above ground.
      • Fire fighters -- working in a complex building under fire conditions need to know where they are regardless of smoke or obscurants.
      • Security - understanding how an area, or volume, has been altered from that originally built or planned might indicate a security weakness or an area that might be of &quot;concern&quot;, such as “hidden” compartments.
  • ARMMIC System (prototype I) GUI data display Motor controller (reuse of 2005 MLR IRaD) Motor arrangement w/laser scanner ARMMIC INITIAL Test System
  • ARMMIC Initial Capabilities Demonstration Note penetration of baffles, vents, fixtures indicate drop ceiling & “real” (concrete) ceiling Scans of small conference room showing operator (baseball capped), and associated “shadow”. Scanner origin
  • ARMMIC Initial Capabilities Demonstration IIz Scanner origin Note subtle structures as tile rails, baffled lighting, and dropped projector Total time duration for scan was 65-70 seconds at resolution (1-degree). A reduced data set option exists; allows for estimated volume (3D box) drawing ; a flattened, 2D output is optional).
