<p align="justify">Cruise missiles are one type of unmanned weapon used to attack a long-range <br /> <br /> target with a precise angle of impact. The flight in the cruise phase is carried out <br /> <br /> at low altitudes with the terrain following guidance system. In the terminal phase, <br /> <br /> the missile aims a specific point on the target. The cruise phase guidance system is <br /> <br /> supported by a stabilization system and a normal acceleration and an altitude <br /> <br /> tracking system. The guidance system for terminal phase is supported by the same <br /> <br /> tracking system but without altitude tracking system. <br /> <br /> The guidance and control systems design is carried out in stages. The terrain <br /> <br /> following system works with 2 algorithms, i.e. weighting equation and moving <br /> <br /> average, to produce guides in the form of flying heights. The impact angle guidance <br /> <br /> system works with proportional navigation guidance law. Control gains of the <br /> <br /> stability augmentation system are designed using linear quadratic regulator <br /> <br /> method. The control augmentation system gains are designed using a PID <br /> <br /> controller. <br /> <br /> The missile that have been equipped with guidance and control systemsis tested in <br /> <br /> cases. The case in cruise phase is done by the missile facing 2 types of obstacles. <br /> <br /> Flight in the terminal phase tested to impact the target from 2 directions. The results <br /> <br /> of the cruise phase test show that the missile can pass the obstacle properly if the <br /> <br /> obstacle characteristics fulfill the maneuver restrictions. Meanwhile, the test <br /> <br /> results in the terminal phase indicate that missile maneuvers is not fast enough to <br /> <br /> follow the guidance, resulting in miss distances. Several methods to restore the <br /> <br /> problem are proposed.<p align="justify">
