This paper presents an intelligent telemetry system using linear array CCD. It is proposed that envelope signals formed by the CCD output pulse series wave serve as the feature of the photogrammetry target. A comparison of the results of a Fourier frequency spectrum analysis for CCD output enveloping curves such as the sine wave, Gaussian wave, rectangular wave and pulse wave makes it possible to conclude that after this kind of method is used in telemetry application in the case of non-image display, the sampling frequency to the envelope signals will be lower, the efficiency will be improved and the resource extravagance will be cut down. By combining computer processing techniques with pattern recognition methods, the extraction, analysis, judgement and recognition of the target features are possible with a smaller amount of data.
