| Abstract: | A measurement system was introduced about initial speed of projectiles based on virtual instrument technology.It stated the operating principle,method of implementation,the hardware and software structure.The wavelet transform was used to perform local analysis in space,and an abrupt change could be detected by model maximum of wavelet transform,the feature point of signal was gotten when projectile passed through sky screen optical target.Experiments proved the feasibility and practicability of the system. |
