6.5 Product Level Measurement (TII-XR)
6.5.1 Introduction
The Transducer Interface Instrument - X-Band Radar (TII-XR) - is the
heart of Enraf’s precision X-band (10 GHz) radar system.
It uses the Frequency Modulated Continuous Wave (FMCW) and
synthesized pulse reflection principle. Using Enhanced Performance
Signal processing (EPS), a smart level detection is possible by filtering
out known obstacles.
