機。 The sum signal and the difference signal modulated by the clock signal are combined to obtain a sum/difference signal, and this sum/difference signal is frequency-converted and phase-detected to form a phase-locked loop. In a tracking receiver configured to detect an error signal according to an antenna angle, a signal spreader is provided that spreads the spectrum of the clock signal, and the spread clock signal modulates the difference signal and detects the error signal. A tracking receiver configured to perform.
