    摘要: The presently disclosed subject matter includes an electromagnetic seeker comprising: an antenna having multiple radiating elements; the antenna is divided into a plurality of sections, each section comprising a group of radiating elements and is directly connected to a respective single power stage configured to provide power to the radiating elements; each section and a respective single power stage are configured to provide a coherent combination of signals transmitted by different antenna sections over the air to thereby enable combination of power from all antenna sections over the air.

    摘要: A tank arrangement including a guided wave radar level gauge installed in a tank, and having a single wire transmission line probe extending through a passage through a conducting structure in the tank. Along the section of the probe that extends through the passage, the arrangement comprises a propagation field limiting structure adapted to reduce a propagation field of an electromagnetic signal propagating along the probe. With this design, the radial extension of the propagating field can be locally reduced so that a sufficient portion of the signal power is allowed to pass through the passage.

    摘要: A radar level gauge system comprising: a transceiver arrangement; a first probe to guide a first transmit signal through a surrounding medium towards a product in the tank, and to return a first surface echo signal, the first probe being configured to guide the first transmit signal with a first propagation velocity exhibiting a first dependence on a dielectric constant of the surrounding medium; a second probe to guide a second transmit signal through the surrounding medium towards the product, and to return a second surface echo signal, the second probe being configured to guide the second transmit signal with a second propagation velocity exhibiting a second dependence, different from the first dependence, on the dielectric constant of the surrounding medium; and processing circuitry for determining the filling level based on the first surface echo signal, the second surface echo signal, and a known relation between the first dependence and the second dependence.
