为了提高脉冲星辐射信号的信噪比，提出了一种基于经验模态分解(EMD)的脉冲星信号去噪算法。
In order to improve the signal-to-noise of the pulsar signal, an algorithm of pulsar signal de-noising based on Empirical Mode Decomposition (EMD) is proposed.
这是探测进动的关键，因为在每次遮挡期间天文学家们可以确定放射线信号的精确角度，并因此断定脉冲星的抖动时间。
That's key to detecting precession, because during each eclipse astronomers can determine the precise angle of the radio signal and therefore the pulsar's wobble over time.
通过天体观测，我们已经确认了银河系里约1800颗脉冲星，其中大部分都能发射出无线脉冲信号，信号的强弱随着这些脉冲星的旋转产生变化。
Sky surveys have identified about 1800 pulsars within the Milky Way, most of which emit pulsing radio signals that rise and fall as the pulsars spin.
除了来自外星人的信号，我们可能还会看到黑洞蒸发或者发现新的脉冲星。
In addition to extraterrestrial signals we might see signs of evaporating black holes or discover new pulsars.
大部分已知的脉冲星只能通过对它们的信号进行' ' '积分' ' '才能找到：对大量的脉冲进行叠加，使得真实的信号可以从背景噪声中分离出来。
Most known pulsars were only found by "integrating" their signal: superposing a large number of pulses in a coordinated way to make the actual "pulse" signal stand out from the "static".
