X-ray pulsar navigation has the characteristics of autonomy, anti-interference, security, etc. For the detection and recognition of X-rays pulsar signals, a new kind of Wolter-I X-ray pulsar detector is introduced. To evaluate the performance of the detector and improve its sensitivity, the Wolter-I X-ray pulsar detector is analyzed through Monte Carlo (MC) simulations. Firstly, based on the Space Environment Information System (SPENVIS), the distribution and spectrum of various particles in the space radiation environment are be obtained. Secondly, the physical model of the Wolter-I X-ray pulsar detector is built in GEANT4, and the response of the detector to the particles including electrons, protons and helium is shown. Finally, taking the shading film of the detector as an example, the optimization method of detector is illustrated. The space radiation background of the optimized Wolter-I X-ray pulsar detector in 700 km on earth circular orbit is acquired. The simulation results show that the space radiation background of the optimized detector is 30.68 cts·s-1.
