Combined System of Phase Synchronization with Increased Astatism order in Frequency Monitoring Mode

The improvement problems for phase synchronization system of phase coherent telecommunication systems and control in radio engineering devices are considered in this work. Namely, the results of the synthesis of open communication in the combined system of phase synchronization are presented under the condition of increasing the astatism order, while monitoring the carrier frequency (pilot signal), the phase of which is modulated by a deterministic Doppler signal. As a result, it is established that keeping in the open channel of the combined system of synchronization for physically realized units, allows to increase the astatism order of the system and to synthesize invariant systems. The frequency discriminator use as an open link allows to increase the astatism order of the combined system of synchronization for the system to the second order. The open channel is made in the form of parallel (sequential) inclusion of two links of the frequency discriminator with the proposed transfer function allows to increase the astatism order to the third and higher order and does not affect the system stability. The effect on the phase error variance of the synchronization system can be achieved by changing the parameters of the disconnected circuit link of the system synchronization.
