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.

What is claimed is: 1. A guidance system for guiding a bullet to a target after it is fired from a gun, said guidance system comprising:a radar unit including a plurality of receiver arrays, said receiver arrays emitting radar signals to the bullet and receiving position signals from the bullet;an optical scope mounted to the gun for optically sighting the target;an inertial measurement unit provided on the gun, said inertial measurement unit identifying a center location of each receiver array in the radar unit;an RF transceiver on the bullet, said RF transceiver including an antenna; andat least one flight actuator on the bullet that controls the direction of the flight of the bullet, wherein the position signals from the bullet received by the radar unit identify the position of the bullet and the radar signal from the radar unit to the bullet provides flight path guidance to change the trajectory of the bullet in response to its position so that the at least one flight actuator directs the bullet towards the target.
