Leida xuebao, 2023 Cognitive radar waveform design often relies on accurate clutter prior information. When prior information data is missing, the constructed clutter model will be severely mismatched, affecting the radar’s ability to suppress clutter.

Joint Design of Transmitting Waveform and Receiving Filter via Novel Riemannian Idea for DFRC System
Remote Sensing, 2023 Recently, the problem of target detection in noisy environments for the Dual-Functional Radar Communication (DFRC) integration system has been a hot topic. In this paper, to suppress the noise and further enhance the target detection performance, a novel

Classification of sags according to their origin based on the waveform similarity [PDF]
2008 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America, 2008 A statistical method for classification of sags their origin downstream or upstream from the recording point is proposed in this work. The goal is to obtain a statistical model using the sag waveforms useful to characterise one type of sags and to discriminate them from the other type.

Search and retrieval method of similar plasma waveforms
Fusion Engineering and Design, 2004 Abstract Fusion plasma experiments often produce many channels of time-varying waveforms, and the assistance of a computational method to find similar waveforms could accelerate data analysis. To accelerate computer aided search, a so-called “thumb-indexed” reference will be required in the waveform database.

IET Radar, Sonar & Navigation, 2022 In this paper, the waveform design for Rician target detection with multiple‐input‐multiple‐output radar is addressed. The relative entropy between the distributions of the observations under two hypotheses is employed as the design metric.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
