7.1.5.11 Non-imaging FMCW Radar / Section 7 Quiz
The measurement result of this FMCW radar is presented either as a numeric value to a pointer instrument or digitized as an alpha-numeric display on a screen. It can be measured only by a single dominant object but with a very high accuracy down to the centimeter range. This method of distance determination is, for example, as used in an aircraft radio altimeter.
Even an analog pointer instrument can serve as an indicator for an FMCW radar (see figure 9). The moving coil meter has a greater inductive impedance for higher frequencies and therefore exhibits a value dependent on the frequency, which is then, however, not linear.
