SYSTEMS AND METHODS OF PROVIDING WHISPER SHOUT SURVEILLANCE WITH A TCAS

摘要

A collision avoidance system is delineated comprising a TCAS transmitter having a feed forward path with a plurality amplifiers for providing to a TCAS transmitter output a TCAS transmitter output transmission, a feedback path coupled to the TCAS transmitter output for providing a feedback signal, and a controller for receiving the feedback signal and generating control signals for providing to one or more of the plurality of amplifiers for controlling the respective outputs of the one or more amplifiers to drive the TCAS transmitter output transmission to a predefined level.
