Abstract
The acoustooptical processor (AOP) is based on an acoustooptical spectrum analyzer with a CCD photodetector operating in a special pipeline operational mode (shift-and-add mode), which allows spectral components of the input signal to be added with a controlled time delay immediately in the CCD photodetector. The proposed AOP was successfully used on an RT-64 radio telescope (Kalyazin Radio Astronomy Observatory FIAN) for the observation of pulsars at 1.4 GHz in a bandwidth of 45 MHz. The frequency scale calibration allows increasing accuracy measurement of time of arrival radioemission pulsar. Experimental results of frequency scale calibration and pulsars profiles for a pulsar PSR 1937+21 are submitted.
