IR countermeasure systems use lasers to confuse the seeker heads on infrared homing missiles. The missiles are guided by Semi-Active Laser Homing or Infrared Imaging. The drone could carry two Mark 44 homing ASW torpedoes. Falcon missiles, which included both infrared homing and semi-active radar homing variants. There are several plans to integrate active radar homing missiles into Kub. Another application was for acoustic homing torpedoes. Pigeon post is the use of homing pigeons to carry messages. Pattern-following and wake homing torpedoes were also developed. An imaging infrared seeker provides target recognition and terminal homing. Taken together the receptor responsible for magnetosensitivity in homing pigeons remains uncertain. Other variants add infrared homing or laser guidance to increase accuracy. Some of the more effective methods used to defeat semi-active homing radar are flying techniques. Later ones used active/passive sonar homing and wire-guidance. Tigerfish homing torpedo, there were doubts about its reliability. Radar Homing and Warning (RHAW) system.
