A method and a system for processing a reflected microwave signal
generated by a radar level gauge system arranged to transmit microwaves
towards the material in the tank, and receive a reflection of said
microwave signal as a tank signal. The tank signal is processes by a
plurality of processes, each process being adapted to determine a process
variable in a specific region of the tank, each specific region
corresponding to a predefined propagation distance range.Such
multi-processing of the received tank signal has the advantage that each
process can be optimized to that particular region of the tank. More
specifically, a process concerned with a particular region of tank only
needs to treat a portion of the tank signal.
