Spectrum sensing algorithm based on stochastic resonance and non-central F-distribution

Dianxin kexue, 2023
To solve the problem that the detection probability of the spectrum sensing algorithm is low and the number of samples required for detection is large at low signal-to-noise ratio (SNR), a spectrum sensing algorithm based on stochastic resonance and non ...

Information divergence-based low probability of intercept waveform detection for multi-antenna intercept receivers

The Journal of Engineering, 2019
Based on the asymptotic spectral distribution of sample covariance matrix, a new low probability of interception (LPI) signal detection method for multi-antenna intercept receiver is proposed via reforming the noise sequence into a Wishart matrix.

Improved probability hypothesis density filter for multi‐target tracking of non‐cooperative bistatic radar

IET Radar, Sonar & Navigation, 2022
Non‐cooperative bistatic radar refers to the passive bistatic radar using a non‐cooperative radar as the illuminator of opportunity. Limited by the non‐cooperation and bistatic configuration, multi‐target tracking of the non‐cooperative bistatic radar is

High-Resolution, Low Probability of Detection Links Through SDRs

IEEE Journal of Microwaves
This paper presents the design and implementation of a low probability of detection (LPD) communication link using a software-defined radio (SDR) platform. The proposed LPD link was tested in an indoor environment using an over-the-air (OTA) network. The

Assessing Population Trends of Species with Imperfect Detection: Double Count Analyses and Simulations Confirm Reliable Estimates in Brown Frogs

Animals, 2022
Most animal species are detected imperfectly and overlooking individuals can result in a biased inference of the abundance patterns and underlying processes.

Performance Analysis for Multichannel Reception of OOFSK Signaling

, 2007
In this paper, the error performance of on-off frequency shift keying (OOFSK) modulation over fading channels is analyzed when the receiver is equipped with multiple antennas. The analysis is conducted in two cases: the coherent scenario where the fading

Camera trap arrays improve detection probability of wildlife: Investigating study design considerations using an empirical dataset. [PDF]

, 2017
Camera trapping is a standard tool in ecological research and wildlife conservation. Study designs, particularly for small-bodied or cryptic wildlife species often attempt to boost low detection probabilities by using non-random camera placement or ...

Single ion implantation for single donor devices using Geiger mode detectors

, 2009
Electronic devices that are designed to use the properties of single atoms such as donors or defects have become a reality with recent demonstrations of donor spectroscopy, single photon emission sources, and magnetic imaging using defect centers in ...

Posterior Probability Matching and Human Perceptual Decision Making. [PDF]

PLoS Computational Biology, 2015
Probability matching is a classic theory of decision making that was first developed in models of cognition. Posterior probability matching, a variant in which observers match their response probabilities to the posterior probability of each response ...
