Miss Distance Analysis of First-Order Explicit Guidance Law with/without Radome effect

Amirhossein Mirzaei; S. Hamid Jalali-Naini; Ali Arabian Arani

Volume 15, Issue 4 , December 2022, , Pages 1-18

  The miss distance analysis of the first-order explicit guidance law (EGL) is carried out using linearized equation of motion in the normalized form in order to obtain normalized miss distance curves. The initial heading error, constant target, acceleration limit, radome refraction error, and fifth-order ...  Read More

Flatness-based Near Optimal Guidance

Reza Esmaelzadeh; Abolghasem Naghash; mahdi mortazavi

Volume 10, Issue 3 , December 2017, , Pages 15-24

  An optimal explicit guidance law that maximizes terminal velocity is developed for the reentry of a vehicle to a fixed target. The equations of motion are reduced with differential flatness approach and acceleration commands are related to the parameters of trajectory. An optimal trajectory is determined ...  Read More
