Simulation and Analysis on 3 D True Proportional Guidance Trajectory

The true proportional guidance principle is briefly presented and 3 D kinematics equation of true proportional guidance law is established. The guidance trajectory decomposed in horizontal and vertical plane is calculated respectively by using fourth-order Runge-Kutta algorithm to synthesize 3D trajectory. The simulated results are accordance with theoretical analysis, which verifies feasibility of decomposition computing 3D guidance trajectory projection. The implementation of algorithm is based on C language, and it provids powerful portability.
