We introduce a reduced basis approach as a new paradigm for modeling, representing and searching for gravitational waves. We construct waveform catalogs for nonspinning compact binary coalescences, and we find that for accuracies of 99% and 99.999% the method generates a factor of about 10-10(5) fewer templates than standard placement methods. The continuum of gravitational waves can be represented by a finite and comparatively compact basis. The method is robust under variations in the noise of detectors, implying that only a single catalog needs to be generated.
我们引入一种约简基方法作为建模、表示和搜索引力波的新范例。我们为非旋转的紧致双星并合构建了波形目录，并且发现对于 99%和 99.999%的精度，该方法生成的模板比标准放置方法少约 10-10(5)倍。引力波的连续谱可以用有限的、相对紧凑的基来表示。该方法在探测器噪声的变化下具有稳健性，这意味着只需要生成一个单一的目录。
