| Abstract: | Based on the engineering background of the simplified guided bomb, considering the guided bomb flying characteristics, the transform relations among different coordinates were investigated, the effects of various Kinds of errors on precision of coordinate transform were analyzed, a coordinate trans?form method based on target tracking was provided. The method can modify the errors, ana improve the coordinate transform precision. The simulation result shows the correctness and feasibility of the method in engineering application. |
