Abstract

In this paper, a predictive guidance algorithm for the mid-course phase of a solid-propellant ballistic missile is presented using discrete laguerre functions. Utilizing predictive guidance significantly reduces the missile impact error compared to conventional methods. However, the computational load for implementation on a flight computer could be a fundamental challenge. For this reason, this research has established and developed a new predictive guidance algorithm based on orthogonal discrete laguerre functions to reduce the computational load while maintaining high accuracy in impact. This approach reduces the parameters describing the predictive guidance law, and the execution time of the algorithm's computations decreases significantly. Through 3D simulation, the impact of using this method for mid-course guidance of a ballistic missile is shown compared to predictive guidance. Additionally, comparing the computational loads of different predictive guidance algorithms demonstrates the advantage of this method in reducing the computational demands.
