As a kind of radar passive jamming equipment， shipborne radio frequency （RF） corner reflector system has been widely installed in the major naval warships of various countries. In order to support the systematic development of Chinese shipborne corner reflector equipment and accelerate the technological innovation of radar-guided anti-ship missiles， the research status and development concept of the two types of corner reflector equipment are reviewed： floating type and airborne type. On this basis， four development trends of shipborne corner reflectors are analyzed and summarized， including launch integration， launch automation， decoy multifunction， and decoy maneuverability.
