PHASE DEMODULATOR AND ITS APPLICATION TO AN MLS-TYPE LANDING SYSTEM

摘要

The invention concerns a demodulator for a phase-modulated wave, for example of the DPSK type, applicable to an MLS system. The demodulator comprises a local oscillator (1) the phase of which is modulated (2). The signal so modified is mixed with the incident signal to be demodulated s(t). The signal emitted by the mixer (5) is applied to a loop (3) the output signal of which controls the phase modulator (2) and constitutes the output signal (Ss) the device.
