Abstract
The application of an acoustooptical correlator for the generation of complicated phase-keyed radio signals by the transformation of the spatial signal of the reference transparency into an electrical signal (this process we will call reading) is described. The electrical signal generated by this method is not completely identical to the signal of the reference transparency; therefore arises the question about the possibility of compressing this signal in the system of the acoustooptical correlator. In the present work this question is investigated theoretically and experimentally. For the optical correlation methods of the generation of complex radio signals it is characteristic to use a reference transparency, whose structure determines the structure of the generated signal. If the question of the reference transparency structure necessary for obtaining a required radio signal during the generation of phase-keyed radio signals, is solved elementarily, in the case of the generation of radio signals with a continuous complex envelope (FM) this question requires special examination.
