The PEARL system locates the enemy arrow by the sound of the shots
The PEARL system, developed by the French company Metravib, is equipped with acoustic sensors that can determine the source of shots during combat. The device is very compact, which allows you to install it on the bar Picatinni or on the helmet.
PEARL captures shock waves that occur during shooting. They spread through the air, like radio emission. With the help of sensitive acoustic sensors, the system determines the direction and place from which the shot sounded. The user will find out about it according to the indications of the LED arrows.
PEARL also determines the azimuth and the angle of elevation of the shots, enabling the fighter to react quickly to the threat. The system provides accuracy of plus or minus 7.5 degrees in azimuth and reacts to medium and small-caliber weapons, that is, from a pistol to 7.62 mm machine guns.
PEARL is designed for fighting in urban conditions and in mountainous terrain, where the sound of shots can be repeatedly reflected from several surfaces. The system also filters out “their” shots from the enemy. It is reliably protected from accidental activation and is controlled by only three buttons.
According to representatives of Metravib, PEARL was tested in several regional conflicts and showed high reliability. Its more advanced version – PILAR details the characteristics of enemy shooting, giving the user the GPS coordinates of the source of the shooting and then displaying it on the map.
