Estimation of radio wave frequency shift and phase incursion on the basis of FPGA in the retransmission meter

Two realizations of data processing system meant for phase shift measurement in the radio wave retransmission measurement system are considered. The model of this system takes into account specific parameters of antennas and radio waves propagation in space. Calculations are performed using methods of diffraction theory. Phase shift measurements are performed according to maximum posteriori probability method on the basis of FPGA EP2C70F672C6. Comparative analysis between demanding resources of the FPGA for this method realization is presented.
