Abstarct: In this thesis, new methods for UAV guidance in the final phase for tracking of moving target is proposed in order to collide with the target. In this study we have utilized the fuzzy inference system to provide effective guidance.The guidance system design is baxsed on concepts of intuitive tracking. Also we suggest an integrated procedure for either far or near distances.This thesis focuses on the design of the guidance system in lateral plane .the commands of desired speed and heading are created instantaneously by the designed fuzzy systems.A specific tracking strategy has been utilized for either with speed control or without it to have the UAV in a proper position in order to collide the target and to have a great performance against the maneuvering of the target.The strategies are baxsed on the position of tracker with respect to the position and velocity of the target. So a new coordinate system is considered and it is called target coordinate system. The position of tracker UAV is computed in this coordinate system.Target coordinate system help tracker UAV to find its position on the basis of target and its speed direction. According to position in target coordination system, appropriate commands for UAV heading and speed are generated.
