Instrumento de busca e rastreamento infravermelho

O sistema de busca e rastreamento infravermelho (IRST) é um instrumento de detecção passiva que detecta e rastreia alvos com base nas características infravermelhas dos alvos de baixa altitude que chegam. O instrumento não é afetado por interferência eletrônica ou desordem e tem forte penetração através da fumaça, boa ocultação, alta sensibilidade e pode funcionar o dia todo e em todas as condições climáticas.

The Infrared Search and Track (IRST) Instrument is a sophisticated sensor system designed to detect, track, and identify targets using infrared radiation, without relying on radar or other radio-frequency-based technologies. This instrument uses infrared sensors to detect heat signatures emitted by objects, such as aircraft, missiles, and vehicles, providing a stealth advantage by operating in a passive mode. The IRST system typically features high-resolution thermal imaging, long-range detection, and precise tracking capabilities, making it invaluable for military, defense, and security applications, where rapid detection of airborne or ground-based threats is critical. It can function in various environmental conditions, including day or night, and is effective in low visibility situations such as fog, smoke, or adverse weather.

The system typically integrates with other tracking systems and radars, providing comprehensive situational awareness. One of the major advantages of the IRST is its passive operation, which enables platforms to remain undetected while tracking high-speed or stealth targets. Its long-range detection capabilities make it ideal for early warning systems and target acquisition, providing superior performance in surveillance, reconnaissance, and defense operations. The instrument's versatility and real-time tracking further enhance the effectiveness of both airborne and naval platforms, significantly improving the success of combat missions and threat neutralization.
