Control is provided to conventional gun-fired projectiles by substituting for the standard fuze thereof a device comprising a canard frame and a main housing, which threads into the fuze well of the projectile, with the canard frame being rotatable with respect to the main housing and having deflectable canards thereon for providing vernier correction on the trajectory to the projectile.

A radiation sensor including an inner detector surrounded by an array of outer detectors is employed in radiation tracking apparatus which is capable of tracking a true target in a field of targets which may include a decoy or false target. The apparatus includes a color filter arrangement and a reticle which cooperates to produce pulses of long and short wavelength filtered infrared radiation upon the outer detectors of the sensor. The apparatus includes means for processing the signals produced by the outer and inner detector elements so as to discriminate between true and false targets and cause the tracking apparatus to track a true target.
