FIRING EVALUATION DEVICE

PURPOSE:To compute the transit point of a bullet accurately even if there is a wind, by correcting the coordinate of the transit point of the shoot bullet according to output data from an anemoscope and anemometer set near a pressure sensor. CONSTITUTION:A position arithmetic unit 5 computes the position of a point in the transit course of a bullet by using previously calculated propagation speed of fire impulse waves, the reach time difference of sound pressure signals 1-3 of fire impulse waves calculated with a reach time difference arithmetic unit 4 and the known coordinate of disposition of a pressure sensor, and determines the position of the point of projectile line on quadrants of a target. At this time, when wind direction and speed signals 6, 7 are input into a position correction conditions deciding part 10, it is decided in which group of the previously classfied sixteen groups of wind according to wind direction and speed the wind belongs, signals corresponding to the names of the group and the quadrant of the target are input into a position correction conditions table part 11, and a corresponding coefficient is selected from stored impulse wave propagation velocity correction coefficients and input into a position correction arithmetic unit 12 to correct the position coordinate of the point in the transit course of the bullet computed with the unit 5.
