What is infrared search and track?
An infrared search and track (IRST) system (sometimes known as infrared sighting and tracking) is a method for detecting and tracking objects which give off infrared radiation (see Infrared signature) such as jet aircraft and helicopters.
How does an infrared radar work?
IR or infrared satellite imagery is sort of a temperature map. The weather satellite detects heat energy in the infrared spectrum (infrared energy is invisible to the human eye). The satellite image displays objects(whether clouds, water or land surfaces) based on the temperature of the object.
What is IRST system?
Infrared search and track (IRST) system is a wide field of view surveillance system, meant for autonomous search, detection, acquisition, and cue of potential targets. The first and second generation IRSTs utilized detectors with multiple elements followed by discrete preamplifiers for signal read-out.
What is an IRST pod?
The IRST pod, known as the Legion Pod, is a sensor that uses the infrared spectrum to help pilots to track and engage enemy aircraft in environments, where traditional radar technology is denied.
How do missile warnings work?
A missile approach warning system (MAW) is part of the avionics package on some military aircraft. A sensor detects attacking missiles. Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to disrupt missile tracking.
What are uses of infrared?
Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.
When was infrared radar invented?
In 1956 Texas Instruments began research on infrared technology that led to several line scanner contracts and, with the addition of a second scan mirror, the invention of the first forward looking infrared camera in 1963, with production beginning in 1966.
Can IR missiles be detected?
To detect approaching missiles, the rocket motor of the missile must be burning – it requires the high effective burning temperatures associated with solid fuel rocket motors. IR-based systems are probably better at altitude but UV is better against surface-to-air missiles.
