Patent ID: 7158072

Claim:
A weather radar signal path for an aircraft, comprising: an antenna ( 105 ), a digital down-converter ( 120 , 121 ), a first transceiver ( 126 ), fiber optic cabling ( 125 ), a second transceiver ( 135 ) and a processing unit ( 130 ), WHEREIN, said antenna is adapted to, in a first mode, receive reflected radar signals from atmosphere ahead, said digital down-converter is coupled to said antenna, said digital down-converter is adapted to convert said reflected radar signals received by said antenna into digital radar signals at a lower frequency, said first transceiver is coupled to said digital down-converter, said first transceiver is adapted to, in said first mode, at least transmit said digital radar signals through said fiber optic cabling, said fiber optic cabling is coupled between said first transceiver and said second transceiver, said fiber optic cabling is adapted to, in said first mode, transfer said digital radar signals between said first and second transceivers, said second transceiver is coupled to said fiber optic cabling, said second transceiver is adapted to, in said first mode, receive said digital radar signals from said fiber optic cabling, said processing unit is coupled to said second transceiver, said processing unit is adapted to, in said first mode, process said digital radar signals to generate weather information based on predetermined algorithm.
