现有的脉冲星信号模拟方法效率低，不适用于大通量或高频率的脉冲星信号模拟，阻碍了X射线脉冲星导航的研究。为了解决这一问题，我们提出了一种基于光子到达时间和光子相位之间关系的快速方法。蟹状星云脉冲星的模拟数据与观测数据的频率绝对差小于10 −4，充分验证了该方法的有效性。该方法比其他方法快3个数量级，具有更高的效率，更好地满足了实时导航验证的需要。
Existing methods for simulating pulsar signals at a spacecraft are inapplicable for large flux or high frequency because of their low efficiency, hindering research on X-ray pulsar-based navigation. To solve the problem, we propose a fast method based on the relation derivation between the photon arrival time and corresponding photon phase at the spacecraft. The absolute differences of searched frequencies between simulated data and observational data for the Crab pulsar are less than10−4, which sufficiently validates the method. Furthermore, the proposed method is up to 3 orders of magnitude faster than other methods, which shows that it is more efficient and better satisfies the needs of real-time navigation verification.
