ECHO CURVE DETERMINATION AT A RESOLUTION THAT DIFFERS ON AN AREA-BY-AREA BASIS

摘要

For the purpose of determining an echo curve using a fill-level measuring instrument operating on the basis of the FMCW principle, the echo curve is calculated from appropriate samples at a first resolution. A particular section of the echo curve is then calculated at a second, higher resolution using the DTFT algorithm. This allows a reduction in the complexity that is necessary for calculating the echo curve.
