Parabolic aerial with a conical diffusion disc for fill level radar

摘要: Reflections on the aerial system of a fill level radar result in reduced measuring quality at short range. Small echo signals range can thus disappear noise. According to one embodiment present invention parabolic for is stated, which comprises mirror, an exciter and diffusion disc. The disc used laterally removing interfering electromagnetic waves that would otherwise be absorbed by exciter. In this way decay behaviour reduced.
