This work describes a method to improve the detection efficiency for continuous gravitational waves by combining information from known pulsars, which emission is too low to be individually detectable. We propose a new ensemble statistic t, which combines statistics from individual pulsars, defined through the five-vector method. Using a collection of band sample data files from the LIGO science run O2, we test the method with software injections in order to study the statistical properties of t. We also study the performance of our method by varying the number of injected signals and their amplitude. We propose and test a possible strategy for the application of the ensemble method to a set of real pulsars.

这项工作描述了一种通过结合来自已知脉冲星的信息来提高连续引力波探测效率的方法，已知脉冲星的发射太低而无法单独探测。我们提出了一个新的集合统计量t，它结合了通过五向量方法定义的单个脉冲星的统计数据。使用来自 LIGO science run O2 的波段样本数据文件集合，我们通过软件注入测试该方法，以研究t的统计特性。我们还通过改变注入信号的数量及其幅度来研究我们方法的性能。我们提出并测试了将集成方法应用于一组真实脉冲星的可能策略。
