Abstract
The new type acoustooptic (AO) processor for observation weak radioemission from cosmic sources - pulsars is developed. The processor is pipeline type one. It executes compensation of a dispersion in broad frequency band. AO pulsar processor consists of AO spectrum analyzer with usage of special pipeline operational mode of CCD, which one allows to execute addition a spectral component of received radio emission with an adjustable dwell in the CCD. The processor used for the first time (June 2002) at Russian radio telescope PT-64 (Kalyasin, Moscow region) FIAN observatory on frequency 1,4 GHz in a band 45 MHz. Experimental results and pulsars profiles are submitted.
