A transponder-based microwave telemetry apparatus for moving machinery includes a microwave transmitter disposed outside the moving machinery to fill a chamber of the moving machinery with microwave energy. The transponder-based microwave telemetry apparatus also includes a transponder disposed inside the moving machinery for measuring a sensed condition of a part of the moving machinery and providing a modulated microwave signal that contains information on the sensed condition. The transponder-based microwave telemetry apparatus further includes a receiver disposed outside the moving machinery to separate modulated and continuous-wave signal components of the signal and extracts information from the modulated component.
