To improve measurement precision and solve the question on projectile information extraction when projectile go through detection screen of photoelectric detection target, the wavelet analysis method was applied to process its information and look for its starting time in screen. The detection principle of photoelectric detection target was analyzed, the characteristic of wavelet analysis method and LMS adaptive filtering algorithm were used to research and analyze the output signal of photoelectric detection target. According to the output signal characteristic of photoelectric detection target, the wavelet transform modulus maxima theory and singularity position point were applied to search out signal's start moment that projectile flying through detection screen, and ensure start moment and calculate time value between detection screens. Base on test velocity principle and experimentation, wavelet analysis method is compared with the traditional nose trigger extraction method, the precision of measuring velocity is less than 0.2%, which verifies wavelets analysis method to extract the photoelectric detection target detection information is feasible and correct. Streszczenie. W artykule analizowane są metody analizy obrazu detekcji fotoelektrycznej w przypadku poruszającego sie szybko obiektu, takiego jak n. pocisk. Do analizy wykorzystano transformate falkową oraz algorytm filtrowania LMS. (Badania mozliwości ekstrakcji informacji z obrazu czujnika fotoelektrycznego przy wykorzystaniu transformaty falkowej)
