The application of proportional navigation in the process of UAV air combat guidance and optimization of proportional parameter

The authors propose a concept of effective attack range to follow the active attacking of Unmanned Aerial Vehicle. An improved proportional navigation model is suggested for being used in the air combat Unmanned Aerial Vehicle guidance model. In addition, the value of proportional parameter is calculated in nonlinear guidance model, and the optimal proportional parameter is confirmed. The simulation results show that the proposed model is effective and quickly.
