1. A meter for use in characterizing signals received by an antenna, the meter including:

  • A. a first subsystem for determining estimates of parameters associated with a direct signal component and one or more multipath signal components of the received signal, the first subsystem determining estimates for one or more of amplitude, delay and phase of the signal components;

    B. a second subsystem for analyzing the parameters and determining if multipath signal components that adversely affect the processing of the direct signal components are present, the second subsystem analyzing a ratio of amplitudes that is based on the estimates of the amplitudes of the direct signal components and the multipath signal components and determining that the multipath signal components that adversely affect the processing are present if the ratio of amplitudes is consistently below a predetermined minimum value over a predetermined time period.
