Ship target far-field scattering simulation error retort identification method based on three-dimensional laser scanning

A ship target far-field scattering simulation error retort distinguishing method based on three-dimensional laser scanning comprises the following steps that a three-dimensional laser scanning mode isadopted, and scanning model data of a ship target are obtained through scanning; the scanning model and the original simulation model are respectively imported into far-field scattering simulation software to carry out simulation calculation of typical working conditions to obtain a scanning model simulation result Q1 and an original simulation model result Q2; the measurement result is subtracted from the corresponding test result Q3 to obtain an absolute value, and |Q3-Q2| and |Q2-Q1| are respectively obtained; a difference limit value deltaQ is set, and an error source is judged through |Q3-Q2|, |Q2-Q1| and the difference limit value deltaQ. According to the scheme, an error source can be found out, and guidance is provided for retort classification and reduction of error causes of various ship targets in the
