Research on one of proportional guidance process based on guidance principle

The proportional guidance method has been widely used in various missiles. However, with the continuous improvement of target maneuverability and the increasingly ugly combat environment, the classical proportional guidance method can no longer meet people's requirements for ballistic parameters, so it is improved and perfected. The proportional guidance law is extremely necessary. In this paper, the establishment of the proportional guidance process based on the guidance principle is studied, and the trajectory established by the classical proportional guidance method and the proportional guidance trajectory based on the guidance principle are designed and simulated, and the simulation results are analyzed. The simulation accuracy analysis is carried out with the example, and the result proves that the proposed method effectively reduces the method error in the calculation of the guidance ballistics.
