Emulating Low Probability of Detection Algorithms

2020 30th International Telecommunication Networks and Applications Conference (ITNAC), 2020
Software Defined Radios (SDRs) can be used to create and modify radio waveforms in order to perform research into various wireless network problems. Defence Science and Technology Group (DSTG) has created the Experimental Framework of SDRs (EFOS) incorporating bespoke SDRs communicating with one another through an RF attenuation matrix.

Minimising RF Detectability for Low Probability of Detection Communication

2018 Military Communications and Information Systems Conference (MilCIS), 2018
This paper describes the need for management of transmission powers in mobile land networks in order to achieve low probability of detection. It explores applicable work in topology control and presents sub-graph search, a localized search method for finding the topology with the lowest detectability footprint.

An empirical probability model of detecting species at low densities

Ecological Applications, 2010
False negatives, not detecting things that are actually present, are an important but understudied problem. False negatives are the result of our inability to perfectly detect species, especially those at low density such as endangered species or newly arriving introduced species.

Low Probability of Detection QS-MC-DS-CDMA for Low VHF

2019 International Conference on Military Communications and Information Systems (ICMCIS), 2019
Tactical military ad-hoc networks usually rely on easily and quickly deployable infrastructure. In such systems reliable communication may be compromised due to imperfect synchronization. QS-MC-DS-CDMA is a solution that allows loose synchrony by employing, so called, LS-codes that are characterized by a zero-correlation zone (ZCZ) that enables ...

Enhanced Distributed Connectivity Control in Low Probability of Detection Operations

2020 Military Communications and Information Systems Conference (MilCIS), 2020
For most military land vehicles, communication systems are the main contributor to RF emissions from the vehicle. To reduce detectability of the vehicle, the transmission power of the communications systems should be managed. Accomplishing this without adversely effecting the ability of vehicles to communicate requires a coordinated approach.
