The invention provides a millimeter-wave radar system, belongs to the technical field of radar imaging, and can solve the problem that an existing millimeter-wave radar system is poor in detection precision. The millimeter wave radar system comprises: an antenna array which is divided into a plurality of groups of antenna units, wherein each group of the multiple groups of antenna units is configured to send radio frequency signals and receive echo signals, and the echo signals are signals returned after the radio frequency signals touch an object; a plurality of radio frequency front ends, wherein the plurality of radio frequency front ends are cascaded, and one of the plurality of radio frequency front ends is connected with one of the plurality of groups of antenna units, and is configured to generate a radio frequency signal, process a received echo signal to obtain echo information, and store the echo information; and a data acquisition unit which is connected with the plurality of radio frequency front
