Improved Algorithm of Radar Pulse Repetition Interval Deinterleaving Based on Pulse Correlation

open access: yesIEEE Access, 2019
In the electromagnetic space, a single channel radar receiver will often intercept several periodic pulse trains radiating from the surrounding emitters simultaneously. The aim of radar pulse deinterleaving is to sort out the pulses coming from different

Synthetic adjacent pulse repetition interval length method to solve integer ambiguity problem: theoretical analysis [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2013
This paper describes a novel approach for realizing femtosecond optical frequency comb (FOFC)-based length measurement. This approach is based on the analogy between the phase unwrapping problem and the integer ambiguity problem. Because the conventional

Interval analysis of repetitive denervation potentials of human skeletal muscle [PDF]

open access: yesJournal of Neurology, Neurosurgery & Psychiatry, 1972
Interval analyses of denervation potentials (fibrillation-potentials and positive sharp waves) in human skeletal muscles were performed using a DEC PDP-12 computer. Extremely small differences between consecutive intervals (usually less than 1%) and slow up and down drifts in the spontaneous discharge frequency were found to be characteristic of ...

Using dispersion-induced group delay to solve the integer ambiguity problem: a theoretical analysis [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2015
This paper describes a novel approach for solving the integer ambiguity problem when the adjacent pulse repetition interval length (APRIL) from a femtosecond optical frequency comb (FOFC) is used as a length scale.

Streaming Codes for Channels with Burst and Isolated Erasures [PDF]

open access: yes, 2012
We study low-delay error correction codes for streaming recovery over a class of packet-erasure channels that introduce both burst-erasures and isolated erasures. We propose a simple, yet effective class of codes whose parameters can be tuned to obtain a

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

open access: yesEURASIP 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.

Radar Signal Deinterleaving in Electronic Warfare Systems: A Combined Approach

open access: yesIEEE 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.
