In real-time signal process it is important to expedite the signal singularity detection for accelerating signal process. By means of detecting singularity points through wavelet transform theory, fast algorithm is deduced on how to identify and process singularity points in real-time signal. This algorithm was implemented to recognize signal singularity points during the sampling intervals without extra time involved. The time complexity of this algorithm is constant. Employing this method in analyzing radar data captured in a rocket launch mission, the data-disappearing and data-recapturing points were correctly and promptly located, which realized accurate locating of data singular points and singularity analysis.
