Projectile target system
First Claim
1. A projectile target range system including:
- at least one target, the or each target having a face arranged to be impacted by a projectile;
the or each target including n pressure wave sensors, wherein n≧
5; and
a processor arranged to receive data from each of said n sensors;
said processor being programmed to operatively;
select different combinations of sensors from said n sensors;
for each combination, analyse the received data to determine a combination output, each combination output being indicative of a potential impact position;
determine whether any determined combination output from any combination varies from the other determined combination outputs from other combinations by at least a predetermined amount, and reject from any further consideration any determined combination output determined to vary by said at least predetermined amount;
determine whether there is a common sensor whose data was used to compute many or all of the rejected combination outputs and, if so, then rejecting all combination outputs including data from the common sensor in determining the impact position; and
analysing non-rejected determined combination outputs to determine a mean output;
wherein said mean output is taken to indicate the impact position.

Abstract
According to one aspect of the present invention, a projectile target is disclosed comprising a target having a substantially sealed chamber having a front face and a rear face with an enclosing side wall disposed intermediate. The front and rear faces are formed by membranes configured to allow a projectile to pass therethrough and then substantially seal to maintain the substantially sealed chamber. Pressure wave sensors are disposed within the chamber and are configured to detect pressure waves created by the projectile. A target controller receives signals from the pressure sensors indicative of the pressure sensed by the sensors and determines an impact point of the projectile on the front face of the target.
