Abstract
The new type acousto-optical processor for observation weak radioemission from cosmic sources -- pulsars is developed. The processor is conveyor type one. It works like 600-channel filter bank receiver with noncoherent (after detection) dispersion compensation in real time. Experimental results are discussed. The processor was used for the first time at Russian radio telescope THA-1500 (Kalyasin, Moscow region).
