Summary:
Remote sensing in contested environments is constrained by power limits, interference, and the need for low probability of intercept. This talk examines sensing architectures that operate using extremely low photon flux, enabling remote measurements while remaining below conventional detection thresholds. Using frequency-comb-based photonic systems, the approach relies on coherent signal structure rather than high transmit power to extract information. Low-flux operation reduces observability, mitigates interference, and enables sensing where traditional active methods are ineffective or undesirable. The discussion emphasizes system-level design and deployment considerations, focusing on transition from laboratory demonstrations to fieldable, dual-use platforms. Applications including precision radar, GPS-denied navigation, and through-obstacle sensing are highlighted.
