Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. [1] Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies.
In order to use infrasound for navigation, it is necessary to be able to localize the source of the sounds. The known mechanisms for sound localizations make use of the time difference cues at the two ears. However, infrasound has such long wavelengths that these mechanisms would not be effective for an animal the size of a pigeon.
Infrasound arrays at monitoring station in Qaanaaq, Greenland.. Infrasound, sometimes referred to as low frequency sound or subsonic, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard). [1]
The General Dynamics FIM-43 Redeye is a man-portable surface-to-air missile system. It uses passive infrared homing to track its target. Production began in 1962 and – in anticipation of the Redeye II, which later became the FIM-92 Stinger – ended in the early 1970s (delivery of the last Redeye for the US Army was completed in July 1971) [2] [3] after about 85,000 rounds had been built.
Infrared homing systems can be decoyed with flares [1] and other infrared countermeasures. Acoustic homing and detection systems used for ships are also susceptible to countermeasures. United States warships use Masker and PRAIRIE (propeller AIR Ingestion and Emission) systems to create small air bubbles around a ship's hull and wake to reduce ...
The V3E A-Darter (Agile Darter) is a modern short-range infrared homing ("heat seeking") air-to-air missile, featuring countermeasures resistance with a 180-degree [4] look angle and 120-degrees per second track rate, [5] developed by South Africa's Denel Dynamics (formerly Kentron) and Brazil's Mectron (now SIATT), Avibras and Opto Eletrônica (acquired by AKAER).

Group meditation and sound baths: reduce stress Mindfulness can feel daunting, but it's necessary for your mental well-being. "Chronic stress can take a toll on our mental health," says Kress.
Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers" since infrared (IR) is just below the visible spectrum of ...
