Infrared (IR) sensors in naval use

Posted by picard578 on November 1, 2016

While they are mostly associated with fighter aircraft, IRST sensors are also used by surface forces, including navies. In naval use, IR sensors are used primarily as early warning devices, which means that shipboard IRST is integrated with ship’s self defense / point defense system. IRST detects targets and sends data to weapons systems, which then engage targets based on pre-determined priorities. In naval use at least, IRST will not replace radars because high humidity at sea level significantly reduces its range. However, it is still an important sensor, especially during the times of radar silence (e.g. threat from anti-radiation missiles). Also of importance is IRST’s immunity to jamming and passive operation, which makes them extremely important in electronically degraded environment. IRST’s shorter operational wavelength means greater resolution, and thus far greater ability to detect small targets as well as to distinguish between the low-flying targets and the background clutter. For these reasons, IRST and IR targeting systems are already in widespread use in air forces for purposes of both air-to-air and air-to-ground combat. Read the rest of this entry »
