基于X射线脉冲星导航（XPNAV）系统的工作原理，设计并实现了一种基于光量子探测的XPNAV硬件在环仿真系统。通过对X射线脉冲星信号的分析，建立了系统的理论模型，提出了脉冲星轮廓累积的Renyi熵方法，并生成了X射线脉冲星信号。实验表明，该仿真系统简单实用，系统产生的观测信号的概率分布与理论结果基本一致。
Based on the principle of the X-ray pulsar navigation(XPNAV) system,a light quantum detection based XPNAV hardware in-the-loop simulation system was designed and implemented.Through analyzing the X-ray pulsar signal,the theoretical model of the system was established,the Renyi entropy method of pulsar profile cumulation was proposed,and the X-ray pulsar signal was generated.The experiments show that this simulation system is simple and practical,and can accomplish the navigation experiments very well.Besides,the probability distribution of the observed signals generated by the system is agreed with the theoretical resut.
