A system for testing a phased array comprising a phase-locked loop circuit responsive to a received output signal of the phased array. The phase-locked loop circuit comprises a phase detector; a filtering element, a variable frequency oscillator and a feedback loop. The system is configured to output at least one of a value indicative of the output of the phase detector and a value indicative of the output of the filtering element for estimating at least one of an imparted phase shift and an imparted frequency modulation by array. |
