- Abstract:
- The bullet speed measuring device is an instrument for measuring the speed of bullets, which is widely used in public security systems, judicial identification departments, gun performance research institutions, etc. For bullet speed measuring devices, speed is the most important parameter. This article provides a method for measuring the speed of a bullet speed measuring device and an analysis of the uncertainty in measurement . There are two methods to calibrate the speed: simulation method and live ammunition method. The simulation method selects a signal generator with a time base relative frequency deviation better than 5 × 10-8 for calibration, and the speed calibration range is (10 ~ 1000) m/s. The live ammunition shooting method uses a time interval measuring instrument with a time base relative frequency deviation better than 5 × 10-8, and the speed calibration range is (40 ~ 250) m/s.
