AM DEMODULATORS AM TRACKING RECEIVERS

DESCRIPTION

The AM demodulators / Tracking Receivers are used to demodulate the modulating frequency from the RF signal received. Such systems are used for moving object tracking where the tracking information is embedded over a carrier of either L-Band  ( 1.435 GHz to 1535 GHz) or S-Band (2.2 GHz to 2.3 GHz). This system will demodulate this tracking information and is fed to the Antenna Control Unit. It has an optional Dual Channel where the both polarization inputs can be fed to the single Receiver systems. This has optional pre-diversity facility where in the output tracking signal will be changed from one channel to other based on the AGC voltage.
