A weather radar signal path for an aircraft. The signal path has an
antenna, a digital down-converter, a first transceiver, fiber optic
cabling, a second transceiver and a processing unit. The antenna is
adapted to, in a first mode, receive reflected radar signals from
atmosphere ahead. The digital down-converter is adapted to convert the
reflected radar signals received by the antenna into digital radar
signals at a lower frequency. The first transceiver is adapted to, in the
first mode, at least transmit the digital radar signals through said
fiber optic cabling. The fiber optic cabling is adapted to, in the first
mode, transfer the digital radar signals between the first and second
transceivers. The second transceiver is adapted to, in the first mode,
receive said digital radar signals from the fiber optic cabling. The
processing unit is adapted to, in the first mode, process the digital
radar signals to generate weather information based on predetermined
algorithm.
