摘要: The invention comprises a direction finding receiving system using a plurality of spaced apart antenna elements mounted in cruciform configuration. Each antenna is connected to an individual receiver, the outputs of which are connected to a broadband digital phase detector. The broadband digital phase detector is used to calibrate the transmission channels and builds a table of phase corrections indexed against an operating frequency. On normal operation, the direction finder measures the frequency of the received signal and retrieves the corresponding phase correction from the calibration memory. The phase measurements are then corrected to yield a more accurate angle of arrival.

摘要: An apparatus and method for combining the functionality of multiple airbone traffic surveillance systems that operate in the L-band frequency range. The apparatus and method combine the functionality of both a Traffic Alert Collision Avoidance System (TCAS) and a Mode Select (Mode-S) transponder in an integrated L-band traffic surveillance apparatus having a single processor that is embodied in a single Line Replaceable Unit.
