Detectability models for multiple access low-probability-of-intercept networks [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2000
Increased demands for communications in the tactical battlefield have driven the development of multiple access low-probability-of-intercept (LPI) networks. Most detectability studies of LPI networks focus on the individual links of the network, in which the intercept and detectability calculations are conducted for a single network transmitter.

Quantum noise limited optical communication with low probability of detection [PDF]

open access: yes2013 IEEE International Symposium on Information Theory, 2013
We demonstrate the achievability of a square root limit on the amount of information transmitted reliably and with low probability of detection (LPD) over the single-mode lossy bosonic channel if either the eavesdropper's measurements or the channel itself is subject to the slightest amount of excess noise.

Cooperative Anti-jamming Method of Data Link Based on Adaptive Threshold [PDF]

open access: yesJisuanji gongcheng, 2018
In order to enhance the anti-jamming capability of data link in low Signal to Noise Ratio(SNR) environment,this paper improves the energy detection method based on invariable threshold and proposes an adaptive threshold anti-jamming method based on ...

On capacity of optical communications over a lossy bosonic channel with a receiver employing the most general coherent electro-optic feedback control [PDF]

open access: yes, 2017
We study the problem of designing optical receivers to discriminate between multiple coherent states using coherent processing receivers---i.e., one that uses arbitrary coherent feedback control and quantum-noise-limited direct detection---which was ...

Ultra-Low Sidelobe Waveforms Design for LPI Radar Based on Joint Complementary Phase-Coding and Optimized Discrete Frequency-Coding

open access: yesRemote Sensing, 2022
In this paper, in order to reduce the probability of the radar waveform intercepted by the passive detection system, the time-bandwidth product of the radar waveform is increased, and the detection probability of the radar waveform to the target is ...

Reduced Memory Region Based Deep Convolutional Neural Network Detection [PDF]

open access: yes, 2016
Accurate pedestrian detection has a primary role in automotive safety: for example, by issuing warnings to the driver or acting actively on car's brakes, it helps decreasing the probability of injuries and human fatalities.

Quantum-noise limited communication with low probability of detection

open access: yesCoRR, 2014
We demonstrate the achievability of a square root limit on the amount of information transmitted reliably and with low probability of detection (LPD) over the single-mode lossy bosonic channel if either the eavesdropper's measurements or the channel itself is subject to the slightest amount of excess noise. Specifically, Alice can transmit $\mathcal{O}(

Refined PHD Filter for Multi-Target Tracking under Low Detection Probability

open access: yesSensors, 2019
Radar target detection probability will decrease as the target echo signal-to-noise ratio (SNR) decreases, which has an adverse influence on the result of multi-target tracking.

Homodyne-like detection for state-discrimination in the presence of phase noise [PDF]

open access: yes, 2016
We propose an innovative strategy to discriminate between two coherent states affected by either uniform or gaussian phase noise. The strategy is based on a homodyne-like detection scheme with photon-number-resolving detectors in the regime of low ...
