ABSTRACT:
A shot simulator using laser light is disclosed for simulating guided missiles. A laser transmitter coupled to a target tracking sight emits differently coded laser signals having different angular deviations from the line of sight repeatedly during at least a substantial portion of the time of flight of the simulated missile. A receiver for laser light reflected from the target is coupled to decoding and analyzing means for calculating the momentary angular deviation of the sight from the target and evaluating these deviations over a substantial portion of said time of flight. Hit indicating means are controlled responsive to the result of said evaluation. The device further comprises means for comparing the angular deviations with stored data representing maximum admissible deviations and/or with an apparent typical target size calculated from a continuously measured actual target distance, means for continuously displaying the relative positions of the target and the sight tracking point, means for differently weighting downward, upward and lateral deviations and means for time averaging the evaluation results over a substantial portion of said time of flight.
