Abstract
Abstract A hit detection system comprising energy-sensitive detectors arranged in an array over a target area of interest. Each detector is connected to a separate amplifier whose output is connected to the input stage of a separate shift register through a threshold circuit. The shift registers are clocked simultaneously by clock pulses from a synchronized clock, the clock pulse period being a function of the time required for energy to traverse a distance which equals the dimension of a hit location area of interest. For each hit location area of interest an AND gate is included. The inputs of each gate are connected to selected stages of the shift register so that only when an impact occurs in the hit location area, associated with the gate, does the latter provide a hit-indicating output.
