Abstract:
An apparatus for determining a health of radio-frequency transmitters each transmitting a transmitted signal during normal operation. The apparatus comprises a receiver for receiving received signals, each received signal responsive to a transmitted signal, a first element for determining signal parameters of each received signal, the signal parameters responsive to an operating condition of a transmitter, each transmitted signal and each associated received signal including an identifier of the transmitter that transmitted the transmitted signal, the apparatus using the identifier to link determined signal parameters with the transmitter that transmitted the transmitted signal and a second element for determining a health of the transmitter that transmitted the transmitted signal, the health responsive to a relationship between one or more signal parameters and a selected value or a range of selected values for each signal parameter.
