technical field [0001] The invention relates to a photoelectric signal simulation error analysis method, which is mainly applied to the analysis and evaluation of the fidelity of optical signal simulation in a semi-physical simulation system of optical guided missiles. Background technique [0002] The analysis and evaluation of optical signal simulation fidelity is the process of determining whether the simulation results can accurately represent the actual system under the application purpose of modeling and simulation, and it is an important way to ensure the credibility of modeling and simulation. The purpose of simulation fidelity analysis is to enable the simulation system to reproduce the behavior of the prototype system to a certain extent, so as to achieve specific simulation purposes. Since the simulation is only a similar or approximate simulation of the actual system behavior, it is necessary to analyze the fidelity of the optical signal simulation so that the si...
