A Midcourse Guidance Method Combined with Trajectory Prediction for Antinear-Space-Gliding Vehicles

Midcourse Trajectory Shaping for Air and Ballistic Defence Guidance Using Bezier Curves

A near-optimal midcourse trajectory shaping guidance algorithm is proposed for both air and ballistic target engagement mission attributes for generic long range interceptor missile. This guidance methodology is based on the maximum final velocity as the objective function and maximum permissible flight altitude as the in-flight state constraint as well as the head-on orientation as the termina...

Midcourse guidance law with neural networks

A dual neural network ‘adaptive critic approach’ is used in this study to generate midcourse guidance commands for a missile to reach a predicted impact point while maximizing its final velocity. The adaptive critic approach is based on approximate dynamic programming. The first network, called a ‘critic’, network, outputs the Lagrangian multipliers arising in an optimal control formulation whi...

A Three Stage Terminal Fuzzy Guidance Law for Reentry Vehicles

An advanced guidance law is developed for reentry phase of a reentry vehicle. It can achieve small miss distance and desired impact attitude angle, simultanceously. To meet this requirment a guidance law based on the fuzzy logic approach is developed. It is partitioned into three stages. This guidance law does not require linearization of missile engagement model. Line-of-sight and flight path ...

A Modified Midcourse Guidance Law Based on Genelarized Collision Course

Optimal Re-Entry Guidance of Space Vehicles

The applicability and the eeciency of a new numerical method for the real-time computation of closed loop controls is demonstrated by the simulation of the guidance of a space vehicle during atmosheric re-entry. This so-called repeated correction method is based on the one hand on the accessory minimum problem or the concept of neighboring extremals and on the other hand on the multiple shootin...
