FIELD: receiving radio signals.
SUBSTANCE: invention relates to the field of receiving radio signals. The technical result consists in the implementation of a coherent detector, which makes it possible to realize an absolute PSK at 180 °. A signal detector with an absolute PSK at 180 ° is proposed, which consists of a sequentially introduced coherent frequency detector (FD) on detuned circuits and a trigger. A coherent BH consists of an annular balanced diode multiplier (ABM) and a low-pass filter (LPF), in which the PSK converted to ASK and the carrier frequency oscillation with PSK are multiplied with each other, while two additional diodes and one secondary winding are introduced.
EFFECT: absolute PSK at 180 degrees achieved.
