Trajectory Design and Guidance Method of Multi-constraint Reentry and Glide section Based on H-V Planning and Gaussian Pseudo-Spectral Method

This paper presents an improved trajectory design and guidance method for long-range anti-aircraft missile re-entry glide segment based on H-V profile. The H-V trajectory of the glide segment is designed as cosine function, and the feasible domain of its key parameters is verified by simulation, which can avoid the problem of singularity of the roll Angle, so that no feasibility analysis and correction are required. By combining the Gauss pseudo-spectral trajectory optimization with H-V trajectory design, a feasible trajectory satisfying the re-entry corridor constraint can be quickly generated.
