Abstract

A remote targeting apparatus and method comprising surrounding a projectile target with a sensor array (10), computing projectile impact data, transmitting the data, receiving the data at a controller, and displaying information corresponding to the data. RF transmission/reception is performed, most preferably at a frequency of between approximately 902 and 928 MHz, with the controller having RF Faraday cage shielding and collision avoidance being employed to permit multiple sensor arrays (10) to operate in a vicinity of one another. Projectile impact locations within twelve inches of the center of the projectile target are calculated to an average RMS accurancy of less than approximately fifty thousandths of an inch, directly in an orthogonal Cartesian coordinate system. Velocity is also determined via an additional sensor (12) at a predetermined distance from the sensor array (10) which measures a difference in time between the projectile passing the additional sensor (12) and the sensor array (10). The preferred sensor array (10) has at least two pairs of acoustical sensors (12) with an additional acoustical transducer (12) orthogonal to the two pairs.
