PURPOSE: To obtain pseudo video display almost in actual form by generating shot pseudo signal, and directly sending it to the reception part of a firearms control system through a waveguide.

CONSTITUTION: An angle signal converter 12 sends data on the direction of a tracking radar antenna 3 to an angle error detector 13. A shot motion parttern gnerator 14 calculates the position of artificial shot and sends angle information on the artificial shot to the detector and distance informationon on it to a shot video level converter. The detector 13 calculates and sends the azimuth and elevation angles of the artificial shot to the transmitted beam of the antenna 3 to the shot video level converter 21. The converter 21 calculates a video level to an antenna pattern generated by an antenna pattern generator and then sends it to an adder 25. The adder 25 adds noises generated by a noise generator and sends the resulting signal to a shot pseudo signal generator 27. The output signal of the generator 27 is sent to a firearms control system receiving part 18 through a waveguide 28.
