1. A system for analyzing an amplitude-modulated signal, comprising:

  • an antenna array that generates at least two antenna beams and an output signal for each of the at least two antenna beams;

    an RF subsystem that processes the outputs for each of the at least two antenna beams and produces at least two channel outputs; and

    a computational subsystem comprising a detector to detect amplitude modulations optionally superimposed on the amplitude-modulated signal, an analog-to-digital converter to generate digital output data, and a digital signal processing unit to analyze said digital output data to characterize a source of the amplitude-modulated signal.
