In order to investigate the impact of high-order intensity correlation of light field on axial moving t arget ghost imaging,this paper uses high-order ghost imaging theory in the research of axial moving target ghost imaging.Firstly,we e stablish a mathematical model of ghost imaging for axial moving target based on ideal thema l high-order intensity fluctuation,and the high-order correlation function is obtained.Then the simulation of mathematical model is carried out by setting different parameters,and the sim ulation images are given.Finally,we compare the image quality by using an evalution parameter o f peak signal to noise ratio (PSNR),and then we analyze and discuss th e silulation images based on the evalution method.The results indicate that high-order intensity correlation of the light field can increase the background noise fluctuation with the increase of the reference beam orde r,and the qulity of reconstructed image becomes worse.Instead ,there is little effect on the image quality with the increase of the signal beam order,but the image quality of ghost imagin g for axial moving target is also degraded.In a word,the best quality can be obtained by the lowest -order ghost imaging.
