Technical field [0001] The present invention relates to the field of simulation data analysis, and in particular, to a semi-real simulation data similarity test method for a weapon system. Background technique [0002] The missile guidance control simulation evaluation test will produce a large number of semi-real simulation test data, and the test data is evaluated by similating the test data, thereby evaluating the design efficiency of the missile guidance control. [0003] For example, a large number of test measurement data generated by the guidance control test, including mathematical simulation test data, semi-real simulation test data, and external flooring data. During the semi-actual simulation test, the mathematical simulation and semi-real simulation test data are needed to detect the similarity test, to determine the consistency of various types of test data, and analyze the calculation results, thereby improving the simulation test method and ballistic design; someti...
