Emulating Low Probability of Detection Algorithms
2020 30th International Telecommunication Networks and Applications Conference (ITNAC), 2020Software 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), 2018This 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, 2010False 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.

Enhanced Distributed Connectivity Control in Low Probability of Detection Operations
2020 Military Communications and Information Systems Conference (MilCIS), 2020For 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.

Low Probability of Detection QS-MC-DS-CDMA for Low VHF
2019 International Conference on Military Communications and Information Systems (ICMCIS), 2019Tactical 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 ...

Low power FSK detection at low probability bit- errors
2008 International Conference on Electronic Design, 2008For portable deep space communications applications where low power is a key requirement At the receiver, non coherent FSK quadrature detectors is suitable that enable to develop novel design and digitally implemented as VLSI circuits An important consideration in an FSK low power receiver is whether to use coherent detection or non coherent detection.

Low probability of detection for underwater acoustic communication
2014 Oceans - St. John's, 2014The ability to avoid detection of a communication signal in the underwater acoustic channel is extremely important for underwater acoustic communication (UWAC) systems when used for military-related applications. Furthermore, low probability of detection (LPD) may reduce environmental impact of UWAC as communication signals can be transmitted at lower ...

Optimal Detection Considerations for Low Probability of Intercept
MILCOM 1982 - IEEE Military Communications Conference - Progress in Spread Spectrum Communications, 1982A variety of receivers which can be used to detect the presence of a wideband (spread) signal in additive white Gaussian noise (AWGN) is explored. The optimality of these receivers is founded upon the knowledge (or lack thereof) of certain key signal parameters.

Chaos for low probability of detection communications
Chaos, Solitons & Fractals, 2017Abstract Many methods for using chaos as a communications signal have been suggested, but all suffer from the difficulty in synchronizing the transmitter and receiver. Chaotic signals are broad band and unpredictable, making them potentially useful when the goal is low interference communications or even low probability of detection (LPD ...
