Abstract
A pulsed radar level gauge comprising a pulse generator configured to generate a transmit signal (S) in the form of a pulse train, a propagation device connected to direct the transmit signal (S) into a tank and return a microwave return signal (S), a receiver, sampling circuitry configured to provide a time expanded tank signal, and processing circuitry for determining said filling level based on the time expanded tank signal. The gauge further comprises impedance increasing circuitry arranged to ensure that an input impedance of the receiver is at least 2 kΩ and a delay line arranged between said receiver and said propagation device, the delay line configured to introduce a delay greater than said pulse duration, such that said time expanded signal includes a transmitted pulse.
