Abstract

PURPOSE:To facilitate the forming of a phase shifter and to attain the phase control by providing the phase shifter to the input of one convolver of two convolvers forming a correlation device and using the phase shifter so as to generate a reference signal with a prescribed phase difference. CONSTITUTION:A CW signal CW1 of the same frequency as that of an RF carrier signal of a reception signal S is given to one input of a multiplier 7 and a phase shifter 9. The phase shifter 9 shifts the CW signal CW1 by a prescribed value and gives the result to one input of the multiplier 8. PN codes PN1', PN2' are supplied respectively to the other input of the multipliers 7, 8 and the outputs of the multipliers 7, 8 become reference signals Rf1, Rf2. The convolvers 5, 6 take the correlation between the signal S with the reference signals Rf1, Rf2 and the correlation outputs Vc1, Vc2 are fed to a demodulation means, e.g., A multiplier 12 to obtain a demodulation signal Vf. Through the constitution above, it is not required for a broad band for the phase shifter 9. Thus, the forming of the phase shifter is facilitated and the phase control is attained.
