The document proposes solutions for improving low-power, wireless, netted sensor networks. It discusses using micro laser radar (MLR) and passive infrared (PIR) sensors that can detect objects at ranges from 100-1000 meters while using low power. The document also proposes using a strategic exfiltration relay infrastructure (SERI) to allow effective sensor data exfiltration and commanding across a widespread network in a scalable way using technologies like GSM cellular networks. It then describes an active 3D micro-scanning laser radar called ARMMIC that can perform localization and volumetric measurements even without GPS to create detailed 3D maps of structures both above and below ground.

7. ARMMIC Performing localization when GPS is absent & providing volumetric measurements on-the-fly

9. ARMMIC Initial Capabilities Demonstration: volumetric measurements in near real-time 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

10. ARMMIC Initial Capabilities Demonstration: volumetric measurements 12 x 12 x 12 ft 3 in 60 seconds 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).
