Radar level meter system

A radar level gauge system includes: a first transceiver; a second transceiver; an antenna arranged to radiate a first transmit signal generated by the first transceiver and a second transmit signal generated by the second transceiver and to receive a first reflected signal and a second reflected signal; a tubular waveguide that directs the transmit signal towards the interface and directs the reflected signal back to the antenna; a plurality of signal interaction structures arranged at different levels along the tubular waveguide to selectively interact with the second transmit signal to facilitate a second reflected signal; and a processing circuit that determines a level of an interface between the liquid-phase product and the gas-phase product based on a relationship between the first emission signal and the first reflection signal, and determines a density distribution based on a relationship between the second emission signal and the second reflection signal. 一种雷达物位计系统，包括：第一收发器；第二收发器；天线，其被布置成辐射由第一收发器生成的
