Abstract

A system for detecting the trajectory of a projectile includes at least one pulsed laser transmitter configured to transmit pulsed laser light beams over a three dimensional area. At least one sensor is configured to sense the pulsed laser light beams reflected off of the projectile. A microprocessor is coupled to the laser transmitter and laser sensor to calculate a first position of the projectile at a first time based upon the first pulsed laser light beam reflected off the projectile and sensed by the laser sensor. A microprocessor calculates a second position of the projectile at a second time based upon a second pulsed laser light beam reflected off the projectile and sensed by a laser sensor. A microprocessor calculates the trajectory of the projectile based upon the first projectile position and the second projectile position and the time differences between these positions.
