System, device, and method for detection of projectile target impact

A target impact detector, comprising:

• a. a sensor array, further comprising at least 2 sensors;
• and
• b. a sensor control unit, which is connected to the sensor array;
• wherein the target impact detector is positioned in a measurement plane parallel to a target plane of a target, as part of a target impact detector installation;
• wherein the sensor control unit is configured with a static calibration corresponding to the target impact detector installation, such that the sensor control unit is configured to calculate an estimated projectile impact location on a target based on a calculated projectile position in a measurement plane, via use of the static calibration, based on measurements from sensors in the sensor array.

A method for target impact detection, comprising:

• a. positioning a target impact detector, wherein a target impact detector is positioned in a measurement plane, such that an elongated direction of the target impact detector is parallel to a plane of the target;
• b. selecting a static calibration, wherein a static calibration that matches with the positioning of the target impact detector relative to the target is selected from a set of predetermined static calibrations;
• c. shooting projectile, wherein a projectile is shot in direction of the target, such that it passes the target impact detector before impacting with the target;
• d. measuring shockwave, wherein measurements are obtained from sensors in the target impact detector, wherein the sensors are measuring a shockwave from the projectile as it passes the target impact detector;
• e. calculating estimated target impact, an optional step or act, wherein an estimated projectile impact location on the target is calculated based on a calculated projectile position in the measurement plane, via use of the static calibration, based on measurements from the sensors.
