Abstract
A radio detection and ranging (RADAR) level gauging apparatus measures a level of liquid in a storage tank. The apparatus includes an antenna that emits a RADAR signal and receives the signal reflected from the level interface. The antenna has a lens and an absorber to reduce side lobes of the signal. The apparatus further includes a controller which performs transmission control, reception control, and level measurement control using the received RADAR signal. The distance from the emission position of the RADAR signal to the level interface is measured, and thus a level can be determined.
