Abstract:
A measurement system w as int roduced about init ial speed of projectiles based on v irtual inst rument technolog y. It stated the operat ing principle, method of implementation, the hardware and softw are structure. T he wavelet transform w as used to perform local analysis in space, and an abrupt change could be detected by model max imum of w avelet t ransform, the feature point of signal was gotten w hen project ile passed through sky screen optical targ et . Ex per-i ment s proved the feasibility and pract icability of the system.
