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.
