LPI waveforms for active sonar?

2004 IEEE Aerospace Conference Proceedings (IEEE Cat. No.04TH8720), 2004
The idea of a low probability of intercept (LPI) waveform is that its form is chaotic. It can of course be recalled by the transmitter (platform), and matched to what is received; but to the target it appears only as noise, and consequently the robust target receiver can only detect a rise in energy.

LPI-BLS: Predicting lncRNA-protein interactions with a broad learning system-based stacked ensemble classifier

Neurocomputing, 2019
Many experiment results show that long non-coding RNAs (lncRNAs) play crucial roles in many biological processes, implementing their functions through interaction with RNA-binding proteins (RBPs).

LPI target tracking involving IEKF

2019 International Radar Conference (RADAR), 2019
We report on strategies and algorithms to track aerial targets with Low Probability of Interception (LPI). We especially focus on the IEKF which is well adapted to maneuvering targets and EKF in log-spherical coordinates to estimate the distance to a target with angle-only measurements.

LPI-labile plasma iron in iron overload

Best Practice & Research Clinical Haematology, 2005
Labile plasma iron (LPI) represents a component of non-transferrin-bound iron (NTBI) that is both redox-active and chelatable, capable of permeating into organs and inducing tissue iron overload. It appears in various types of hemosiderosis (transfusional and non-transfusional) and in other iron-overload conditions.

Automatic Recognition of General LPI Radar Waveform Using SSD and Supplementary Classifier

IEEE Transactions on Signal Processing, 2019
For low probability of intercept (LPI) radars, frequency-modulated and phase-modulated continuous waveforms are widely used because of their low peak power compared to that of pulse waves (PW).

Vakinhoudelijk leiderschap en de LPI

Nederlands Tijdschrift voor Evidence Based Practice, 2010
» Om vakinhoudelijk leiderschap vorm te geven kan gebruikgemaakt worden van de sleutelelementen van transformationeel leiderschap. De essentie van transformationeel leiderschap is het bereiken van organisatieverandering door het benadrukken en creeren van nieuwe waarden en een gezamenlijke toekomstvisie.

Feature Extraction of Intra-Pulse Modulated LPI Waveforms Using STFT

IEEE International Conference on Recent Trends in Electronics, Information & Communication Technology, 2019
LPI radar is a class of radar systems that has the ability ‘to see and not to be seen’ i.e. because of certain characteristics that make them nearly invisible to intercept radars.

LPI Radar Sinyallerinin Ozimge Yaklasimi ile Siniflandirilmasi Classification of LPI Radar Signals via Eigenimage Approach

2007 IEEE 15th Signal Processing and Communications Applications, 2007
Low Probability of Intercept (LPI) Radar signals have the property of wide bandwidth, low peak power to make them difflcult to be detected by Electronic Support Measures (ESM) receivers. In this study, the detection performances of LPI Radar signals with Wigner-Ville Distributions are examined by treating each distribution as an image.

LPIdomains and Pullbacks

Communications in Algebra, 2014
In this paper, we will investigate a question of Anderson–Zafrullah of whether an LPI domain (every nonzero locally principal ideal is invertible) has finite prime character and characterize pullbacks that are LPI domains.

LPI waveform design using chirplet graphs

OCEANS 2015 - MTS/IEEE Washington, 2015
The Low Probability of Intercept (LPI) signals are of great interest in underwater acoustics. LPI signals are designed such that their presence is difficult to detect, hence taking countermeasures against them are less likely. The traditional method of LPI waveform design is to spread the signal energy in time and/or frequency thus making it ...
