Guided projectiles arise at the historic moment. Guided projectiles both have the advantages of traditional projectile and missile，it is a combination of conventional ammunition and high-tech military technology. It has become the inevitable trend of future artillery weapons. In this paper, a guided projectile with canard configuration was chosen as the prototype, Simulating the guided projectile ballistic curve in different guidance law by computer. Analyzing and comparing the characteristics of ballistic curve of the tracking law, and proportional guidance law and over gravity compensation proportional guidance. From the pictures, the ballistic of proportional guidance is flatter than that of tracking law. Guided projectile can attack the top of the target by use of the over gravity compensation proportional guidance law.
