Abstract
Methods and systems for determining fluid levels in a tank comprise a mmWave control unit configured to generate and transmit a millimeter wave chirp. The control unit transmits the chirp into the tank through a Luneburg lens and receives one or more chirp reflections from the tank. For each tank level reading, three or more chirp configuration profiles are used in order to ensure accurate depth measurements due to multi-path reflections in most tanks. The control unit mixes the chirps with the chirp reflections to generate a set of responses for each chirp configuration profile. The responses are compared and the two best responses are selected and averaged. The set of averaged responses are then processed using a ballot and vote process to determine the distance reading that is likely to provide the most accurate tank level.
