Real-time test system for long range moving targets

More Information
  • A real-time test system for moving targets was designed to test the system coordination accuracy of weapon system operating at 0-fly mode, and measure the tracking and pointing error. In the surveillance of long range moving targets, the system adopted double optical paths, a binocular tube of long focus and short focus, and an electric switching device to carry out the real-time observation for long and short range targets. The binocular tube was installed at the same machine body to ensure the concentricity by means of eccentric frame and eccentric ring. The fixture had fine tuning mechanism of pitch and azimuth to regulate the boresight between optical axis and gun axis. The measurement data with high precision and high fidelity were obtained. The static angle measurement accuracy of the tubes with 50 mm and 300 mm focal length was tested, and the experimental results showed that the accuracy was less than 0.4 mrad and 0.2 mrad respectively, which met the target requirements. This modular test system is reliable and can be widely used in military and civil applications.
