Abstract: A weapons engagement simulation system includes a weapon simulator having a laser transmitter for transmitting pulses of directed coherent light in a characteristic temporal pattern and a receiver garment. A plurality of photosensitive detectors distributed over each of a plurality of discrete zones on the outside of the garment respond to light from the laser transmitter by producing electrical detection pulses systematically related thereto. Comparators compare the electrical detection pulses from the photosensitive detectors in a respective zone with a predetermined threshold level and produce discriminated detection pulses when said electrical detection pulses are greater than the threshold level. A decoder compares the temporal patterns of the discriminated detection pulses with a temporal pattern characteristic of the laser transmitter and produces a hit signal corresponding to a respective corresponding zone when the compared patterns correspond.
