This book contains the background history of a Target locking system, the components description used in designing this system. It also contains the software development portion, software which we have programmed, their flowcharts and explanations. At the end of the thesis we have given the conclusions, our experience, future enhancements that can be done in this project and recommendations that can take this project to a much higher level. The main and by far the most important goal which we want to achieve is the implementation of a target locking system in real time with the following characteristics; ? To design a stable hardware of Target Locking system that can be cover maximum area. ? Design should be capable of handling any future advancement in the operating system. ? The cost of Target Locking system should be less than the that available in the market, but should provide more features than them.
