Radar Signal Deinterleaving in Electronic Warfare Systems: A Combined Approach

IEEE Access, 2023
Traditional deinterleaving algorithms first cluster the pulses in frequency, pulse width, and angle of arrival parameter space. Then, they utilize time of arrival analysis techniques.

Generation of the transport service offer with application to timetable planning considering constraints due to maintenance work [PDF]

, 2019
Line planning is an important step in strategic timetable planning in public transport. In this step the transport offer for the customer is generated by the public transport operator, whereby the resulting costs for the operator should be as deep as ...

Interference Mitigation Technique for Coexistence of Pulse-Based UWB and OFDM

EURASIP Journal on Wireless Communications and Networking, 2008
Ultra-wideband (UWB) is a useful radio technique for sharing frequency bands between radio systems. It uses very short pulses to spread spectrum. However, there is a potential for interference between systems using the same frequency bands at close range.

Fair Repetitive Interval Scheduling

Algorithmica
Abstract Fair resource allocation is undoubtedly a crucial factor in customer satisfaction in several scheduling scenarios. This is especially apparent in repetitive scheduling models where the same set of clients repeatedly submits jobs on a daily basis.

Interval between item repetitions and free recall memory [PDF]

Psychonomic Science, 1967
The interval between two presentations of the same item has a marked effect on paired associate learning (e.g., Greeno, 1964) but has been reported to have no effect on free recall (Waugh, 1963). To explore this apparent contradiction, a free recall experiment was performed with a mixed list of words and nonsense syllables in which the interval between

Encoding of temporal information by timing, rate, and place in cat auditory cortex. [PDF]

PLoS ONE, 2010
A central goal in auditory neuroscience is to understand the neural coding of species-specific communication and human speech sounds. Low-rate repetitive sounds are elemental features of communication sounds, and core auditory cortical regions have been ...

Human middle temporal cortex, perceptual bias, and perceptual memory for ambiguous three-dimensional motion [PDF]

, 2010
When faced with inconclusive or conflicting visual input human observers experience one of multiple possible perceptions. One factor that determines perception of such an ambiguous stimulus is how the same stimulus was perceived on previous occasions, a ...

The role of scheduled second TACE in early-stage hepatocellular carcinoma with complete response to initial TACE [PDF]

Clinical and Molecular Hepatology, 2017
Background/Aims We investigated the outcomes of early-stage hepatocellular carcinoma (HCC) patients who showed a complete response (CR) to initial transarterial chemoembolization (TACE), with a focus on the role of scheduled TACE repetition.

Recognition and parameter estimation of spaceborne synthetic aperture radar pulse repetition interval modulation based on short time modified pulse repetition interval transform

IET Radar, Sonar & Navigation, 2022
Abstract The traditional pulse repetition interval (PRI) transform method and modified PRI transform method have a low ability to recognise the complex PRI modulation type adopted in spaceborne synthetic aperture radar systems. To solve this problem, a short‐time modified PRI transform (STMPT) method based on the traditional PRI ...
