System dynamics of a 24 GHz and an 80 GHz FMCW Radar Level Transmitter

System dynamics using the example of low reflective media: A metallic sphere represents a conceivably weak reflector, since only a small part of the radiated signal is reflected back in the direction of the antenna. Thus, a sphere can be used to simulate reflections on products with low dielectric constant, the so-called DK value. First, the metallic ball sphere is inserted under the 24GHz device. In the spectrum recording, the reflection on the spherical surface is clearly recognisable. Now the ball sphere is placed under the 80 GHz radar transmitter. Here again, the reflection of the sphere is immediately visible. Since both radar devices are FMCW systems, the devices have comparable dynamics as expected. The reflection on the spherical surface corresponds to a DK value of approximately 1.2 and is clearly recognisable with the 24GHz as well as with the 80GHz system.
