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.

Detection of multiple access low-probability-of-intercept networks
Proceedings of TCC'94 - Tactical Communications Conference, 2002Increased demands for highly connective, yet covert, communications in the tactical battlefield have fueled the development of so-called multiple access low-probability-of-intercept (MALPI) networks. Although there have been a number of research efforts regarding the design of MALPI networks, detectability analyses are typically carried out for a ...

Low probability of detection underwater acoustic communications for mobile platforms
OCEANS 2008, 2008Mobile underwater platforms, such as autonomous underwater vehicles (AUVs), use underwater acoustic communications to form a network for command and control. Direct sequence spread spectrum signaling can be used for multi-access communications. It also provides high processing gain for communications using a low source level.

A method and metric for quantitatively defining low probability of detection
IEEE Military Communications Conference. Proceedings. MILCOM 98 (Cat. No.98CH36201), 2002The lack of a low probability of detection (LPD) waveform is often cited as one of the criteria against the use of commercial off-the-shelf (COTS) communications systems in the tactical military environment. However, there is rarely any quantitative evidence given to support this understandable qualitative assertion.

Asymptotically Optimal Detection of Low Probability of Intercept Signals using Distributed Sensors
IEEE Transactions on Aerospace and Electronic Systems, 2012An asymptotically optimal technique for detection of low probability of intercept (LPI) signals using multiple platform receivers is proposed. This is a centralized detector unlike the commonly used decentralized decision fusion techniques and is an extension of Stein's [1] results from two sensors to multiple sensors.

Low probability of detection underwater communications using a vector sensor
2022 Sixth Underwater Communications and Networking Conference (UComms), 2022Low probability of detection underwater acoustic communications are required for command and control of mobile underwater platforms performing covert missions. To deal with multipath and increase the signal-to-noise ratio (SNR) at the receiver, this paper presents a study on the low probability of detection communications using a single vector sensor ...

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.

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 ...
