Abstract
Abstract A synthesized target system utilizes emitters in the microwave or laser frequency for generating an electromagnetic energy curtain. Detectors are operatively disposed for detecting reflections within the energy curtain caused by penetrations of the curtain by one or more projectiles. A monitor is connected to the output of the detectors, and a recorder is used for storing the data output of the monitor. The event of passage of projectiles through the energy curtain, and their location upon penetration thereof, is monitored, scored, recorded and can be printed out, in hard-copy form, in real time. Physical targets and down-range human intervention therewith are eliminated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
238 words
A synthesized target system comprising: a power supply means for providing electrical energy to said target system; overlapping emitter means for generating a target plane in the form of an electromagnetic energy curtain; overlapping zone detector means operatively disposed in said target plane for detecting reflections from a plurality of projectiles, for simultaneously detecting the positions of said projectiles within said target plane, for determining the order in which said projectiles penetrate said target plane, and for generating electrical output signals in response to said reflections; monitoring means electrically connected to said amplifying means for instaneously observing the position of said projectiles in said energy curtain which includes; trigger means for monitoring a separate output signal for each projectile reflection, for discriminating between said projectiles and background noise, and for blocking spurious signals; and pulse shaping means for broadening the width of said amplified detector output signals; recording means for generating real-time archival records for storage and retrieval of the data output of said pulse shaping means; and rails means for protecting and holding said emitter means and said detector means operatively disposed about said target plane which includes; a portable first optical rail member disposed along an x-axis of said target plane; a portable second optical rail member disposed along a y-axis of said target plane; and disconnect joint means for providing easy and accurate erection and optical alignment of said first and second portable rail members.
