A guidance system for actively guiding a projectile, such as a bullet after it has been fired from a gun. The guidance system includes a radar unit that includes a plurality of receiver arrays. An optical scope is also mounted to the gun for optically sighting a target. An inertial measurement unit provided on the gun locks onto the target after it has been sighted by the scope, and provides a reference location at the center of the receiver arrays from which the bullet can be directed. The receiver arrays receive radar monopulse beacon signals from the bullet. The signals from the bullet are used to identify the position of the bullet and the roll of the bullet. The signals sent to the bullet provide flight correction information that is processed on the bullet, and used to control actuators that move steering devices on the bullet.
