Target Tracking While Jamming by Airborne Radar for Low Probability of Detection [PDF]

open access: yesSensors, 2018
Although radiation power minimization is the most important method for an advanced stealth aircraft to achieve the low probability of detection (LPD) performance against the opposite passive detection system (PDS), it is not always effective when the ...

Detection of Signals with Chaotic Varying Forms and Low Intercept Probability

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники
Low probability of intercept performance of direct-sequence spread-spectrum system with chaotic spreading sequences is investigated. The energy detectors, synchronous and asynchronous, coherent and non-coherent structures are studied here to detect the ...

Superimposed training low probability of detection underwater communications [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2020
This paper proposes a superimposed training method for low probability of detection underwater acoustic communications. A long pilot sequence was superimposed to the message for equalization and synchronization purposes. A fast Hadamard transform (FHT) estimated the channel impulse response and compressed the pilot energy.

Low Probability of Detection for Underwater Acoustic Communication: A Review [PDF]

open access: yesIEEE Access, 2018
Low probability of detection (LPD) is an extremely important characteristic of an underwater acoustic communication (UWAC) system when used for military-related applications, since the detection of a communication signal in the channel may reveal the ...

Fundamental Limits of Communication With Low Probability of Detection [PDF]

open access: yesIEEE Transactions on Information Theory, 2016
This paper considers the problem of communication over a discrete memoryless channel (DMC) or an additive white Gaussian noise (AWGN) channel subject to the constraint that the probability that an adversary who observes the channel outputs can detect the communication is low.

Performance Comparison of Relay-Based Covert Communications: DF, CF and AF

open access: yesSensors, 2023
In this paper, we investigate the performance of covert communications in different types of a relay system: decode-and-forward (DF), compress-and-forward (CF) and amplify-and-forward (AF).

Time Series Data Anomaly Detection Based on Total Variation Ratio Separation Distance [PDF]

open access: yesJisuanji kexue, 2022
Anomaly detection for time series data is one of the important research problems in data analysis.Its main challenge is to detect if there are any anomalies and locate anomalies with low delay according to context.Most of existing anomaly detection ...
