Date Mar. 9, 1989.Disclosed is a demodulator for a phase-modulated wave, of the DPSK type for example, applicable to an MLS system. It has a local oscillator, the phase of which is modulated. The signal thus modulated is mixed with the incident signal to be demodulated. The signal coming from the mixer is applied to a loop, the output signal of which: controls the phase modulator; constitutes the output signal of the device.
