IRST stands for Infrared Search and Track. It is a technology used in military and aerospace applications to locate and track targets through the use of infrared radiation. The purpose of IRST is to detect, identify, and track airborne targets, especially enemy aircraft, by utilizing their heat signature, or thermal emissions.
IRST systems are typically composed of infrared sensors or detectors that are capable of detecting the infrared radiation emitted by objects, even in low-light or no-light conditions. These systems usually consist of a sensor or a set of sensors, processing units, and display units.
The IRST technology differs from other traditional tracking methods, such as radar, as it does not rely on electromagnetic waves to detect and track targets. Instead, the infrared sensors detect the thermal radiation emitted by the objects. This makes it a valuable stealth technology, as it is difficult for enemy aircraft to detect an IRST system in operation.
IRST systems can provide vital information to operators, such as the target's location, speed, altitude, and even the type of aircraft. This information can be used for various purposes, including threat assessment, target prioritization, and weapon system engagement.
IRST technology has significantly enhanced the capabilities of military and aerospace systems, enabling more accurate and effective target detection and tracking, particularly in situations where radar might be less effective or compromised.
