In this thesis, a tactical missile is required to reach the target while satisfying prescribed impact-angle and impact-speed conditions. To this end, a phase-based hybrid framework is developed. During the ascent phase, trajectory shaping is employed to improve the maneuver margin available for the subsequent glide and terminal phases. In the glide phase, an online impact-speed predictor is integrated to support satisfaction of the terminal speed requirement. In the terminal phase, a guidance approach targeting a near-zero angle of attack at impact is derived, and achievement of the terminal conditions is verified through simulation results. On the control side, the inner two loops of the classical three-loop autopilot architecture are retained, while Active Disturbance Rejection Control (ADRC) is incorporated in the outer acceleration loop to improve robustness against aerodynamic uncertainties and external disturbances. The proposed method is evaluated via simulations under different scenarios and uncertainty conditions, and the results are presented.
