Abstract

By using the advantage of two different and orthogonal polarization directions and sending pulses with different polarization alternately you can send out a new pulse towards the echo without waiting on the return of the previously sent pulse. This will give us the advantage of two times more pulses in the echo without the need of limiting the measuring distance and we will get twice as much energy back in the receiver. The system can also analyze the two different channels separately in order to get a more robust situation when the surface isn't calm or when a liquid surface to be measured passes a disturbance echo caused by for instance an internal support structure in a tank.
