Compressed Sensing for Time-Frequency Gravitational Wave Data Analysis
摘要:
通过与现有方法的比较,说明了压缩感知在获得用于引力波数据分析的稀疏时频表示方面的潜力,关于i)揭示噪声瞬态的精细结构在准备分类时,和ii)在使用受以下影响的检测器网络检测未建模的瞬态引力波信号时提高波形一致性测试的性能未建模噪声瞬态
英文摘要:
The potential of compressed sensing for obtaining sparse time-frequency representations for gravitational wave data analysis is illustrated by comparison with existing methods, as regards i) shedding light on the fine structure of noise transients (glitches) in preparation of their classification, and ii) boosting the performance of waveform consistency tests in the detection of unmodeled transient gravitational wave signals using a network of detectors affected by unmodeled noise transient
