    Appendix A: Technical Reference Principles of Operation SITRANS LR460 is a long range FMCW (Frequency Modulated Continuous Wave) radar transmitter. Radar level measurement uses the time of flight principle to determine distance to a material surface. FMCW radar transmits a continuous wave. The frequency of the wave is constantly increasing: this is known as the sweep.
