Very little has been disclosed to date on the HQ-64/LY-60 engagement radar, with the system first being displayed publicly in late 2008 (above). This radar is primarily a Continuous Wave X-band illuminator for the monopulse semi-active homing LY-60 missile round, a reverse engineered Aspide Mk.1 (AIM-7 derivative). The simplicity of the fixed single horn feed makes it unlikely that this radar includes a monopulse precision angle tracking capability often seen in Russian CW tracker/illuminator designs.
