IRST: The revolution in infrared search and tracking systems



Download report

Infrared search and tracking technology, known as IRST (Infra Red Search & Track), has undergone significant advancement in recent years, providing a crucial tactical advantage in defense and security situations. This article will deal with the characteristics and benefits of IRST systems, their applications in different contexts and the solutions offered by Grupo Oesía.


The advantage of seeing without being seen: How does it work?

IRST systems are detection and tracking devices based on passive infrared sensors, which means that they can detect and track targets without emitting any signal, such as radar or communications. This “see without being seen” capability offers a significant tactical advantage in complex operational environments, as it enables airborne and maritime platforms to detect and track high-speed targets, such as missiles, or small targets, such as drones, without revealing their position.

IRST systems work by detecting infrared radiation emitted or reflected by objects. Infrared radiation is a form of electromagnetic energy that is in a longer wavelength spectrum than visible light. Infrared sensors are able to detect temperature differences between objects and their environment, allowing them to identify and track targets based on their thermal signature.


Aeronautical and naval applications

IRST Aeronautics

IRST systems for aerial platforms are a passive infrared tracking solution that provides early warning and automatic multi-target tracking capability in aerial environments. These systems are integrated into combat aircraft, allowing pilots to detect and track targets over long distances without being detected by enemy or warning systems.

In addition, aeronautical IRST systems are used in aerial reconnaissance and surveillance missions. The ability to detect targets without emitting signals facilitates obtaining real-time, high-quality information about the operational environment without alerting potential adversaries.

IRST Naval

Similarly, IRST systems for naval platforms offer passive infrared tracking capabilities for ships and submarines. These systems enable naval units to identify and track targets at sea and in the air, providing a tactical advantage in reconnaissance, surveillance and defense missions.

In the naval field, IRST systems can also be used in the detection and tracking of submerged objects, such as submarines and unmanned underwater vehicles. The ability to operate without emitting signals is also essential in the underwater environment, where discretion is key to mission success and unit survival.


IRST in terrestrial and security applications

IRST systems can also be applied in terrestrial environments and security missions. On the ground, IRST systems can be used in military vehicles and fixed or mobile surveillance systems to detect and track targets on the ground and in the air. These systems provide ground forces with a valuable tool for intelligence, surveillance and reconnaissance, as well as real-time target identification and tracking.

In terms of security applications, IRST systems can be used in the protection of critical infrastructure such as power plants, government facilities and airports. The ability to detect and track objects without emitting signals facilitates unobtrusive surveillance and rapid response to potential threats.
