The dynamic simulating process of sight-seeing angle of the pop-up stem in high-frequency laser jamming test of laser-guided weapon against semi-physical simulation system was studied. The complete process of simulation accuracy analysis of pop-up line of sight was analyzed. The geometrical error, the control error and the error source of the optical system which affect the simulation accuracy of the pop-up line of sight are analyzed in detail. A simulation error model of the sight line angle of the bullet is established by using a multi-body system error analysis modeling theory. The test method of the simulation error of the sight line is designed. By combining the error modeling with the experimental test, the error term in the simulated error model can be obtained. The method of residual analysis or Monte-Carlo simulation is proposed to analyze the accuracy of the simulation of the pop-up line-of-sight angle, and the estimated value and the variation rule of simulation error of line-of-sight are obtained.
