1. A method for determining at least one physical parameter of a system with at least two reflection objects, comprising:
generating a transmission signal comprising at least one modulated wave;
receiving a first reception signal, wherein the first reception signal is based on the transmission signal reflected by a first reflection object;
receiving a second reception signal, wherein the second reception signal is based on the transmission signal reflected by a second reflection object; and
determining the at least one physical parameter of the system based on the first reception signal and the second reception signal, wherein determining the at least one physical parameter of the system occurs without including the transmission signal.
