Dynamic Sensor-Tasking and Routing System for Subsurface Hazard Detection

Solicitation # DTR27BZ02-NV003

The Defense Threat Reduction Agency is soliciting a Phase I SBIR proposal for a Dynamic Sensor-Tasking and Routing System to enhance the detection and defeat of subsurface WMD devices and components. Current operational capabilities suffer from a collect-everything bottleneck where unmanned platforms use static scripts that flood tactical networks with raw data and fail to adapt to changing soil physics. To resolve this, the agency requires an explainable, adaptive machine-learning architecture using Super Intelligence to dynamically schedule, sequence, and gate geophysical sensor modalities. This decision engine must utilize probabilistic methods, such as reinforcement learning, contextual bandits, or partially observable Markov decision processes, to optimize sensor deployment at the edge based on real-time environmental physics and mission constraints. This total small business set-aside solicitation, numbered DTR27BZ02-NV003, focuses on the Trusted AI and Autonomy priority area and requires CMMC Level 1 compliance. Proposals must be submitted via the DoW SBIR/STTR Innovation Portal (DSIP) and are evaluated based on technical merit, investigator qualifications, and commercial potential. The project aims to move beyond stove-piped visual mapping and post-processing suites toward a closed-loop system that can autonomously verify threats and adjust routing in uncharacterized environments. Successful development will lead to large-scale field demonstrations in Phase III to ensure reliable subsurface hazard clearance while minimizing operator exposure and network saturation.
