Measurement of atmospheric refractivity using signals of opportunity
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012High-resolution numerical weather models require fine-scale (1–5 km) measurements of moisture fields over large areas (>20,000 km2). Existing techniques such as GPS are not able to meet these requirements. This paper discusses the feasibility of a novel method for measuring atmospheric refractivity by the opportunistic reception and processing of ...

Anomaly Detection Using WiFi Signals of Opportunity
2019 13th International Conference on Signal Processing and Communication Systems (ICSPCS), 2019Detection of changes in indoor areas and controlled environments is getting increasing interest in ambient intelligence and security. In this paper, we propose a radio-frequency (RF)based anomaly detector that, observing the spectrum received from signals of opportunity (SoOp) and exploiting machine learning (ML) techniques, is capable of revealing ...

Signal Encryption Opportunities for Photonic Networks
OSA Advanced Photonics Congress (AP) 2020 (IPR, NP, NOMA, Networks, PVLED, PSC, SPPCom, SOF), 2020We discuss signal encryption opportunities in photonic networks (PNs). In particular, we use computer simulations to show that dynamic keys lead to diffusion when two phase-encoded signals are shuffled and transmitted through PNs.

Cannabis and Cannabinoid Signaling: Research Gaps and Opportunities
The Journal of Pharmacology and Experimental TherapeuticsCannabis and its products have been used for centuries for both medicinal and recreational purposes. The recent widespread legalization of cannabis has vastly expanded its use in the United States across all demographics except for adolescents. Meanwhile, decades of research have advanced our knowledge of cannabis pharmacology and particularly of the ...

Bistatic Radar Equation for Signals of Opportunity Revisited
IEEE Transactions on Geoscience and Remote Sensing, 2018The bistatic radar equation currently used for simulating surface-reflected waveforms or delay-Doppler maps (DDMs), produced by signals of opportunity from global navigation satellites system (GNSS) or communication satellites, was previously derived under some limiting assumptions.

Exploiting Signals-of-Opportunity for the Synchronization of Moving Sensors
2018 IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2018Positioning and communication systems rely on synchronization processes that are expensive in terms of time, energy and resources. A novel localization algorithm has been recently developed for the synchronization of static sensors [1]. This algorithm exploits time-delay measurements of signals-of-opportunity of static sources at unknown locations ...
