Launcher unit |
The main component of the towed DY-90 station is the launcher unit, which is carried on a two-wheeled A-frame trailer. When in the firing position, the wheels are removed from the ground and the trailer is stabilised on four adjustable outriggers. The launcher unit consists of a one-man firing cabin station mounted on the left side of the trailer and four missiles ready to fire on the left side of the cabin.

Operations |
The surveillance radar detects the target aircraft and then hands it over to the appropriate tracking/illumination radar unit for the engagement. The system continuous wave semi-active homing guidance principles, and, with the allocated assets, the battery can process up to 40 targets, track 12 and engage three of them simultaneously. The use of the moving target tracking processing system and frequency agility technology also gives the system good anti-jamming capability. System reaction time is 9 seconds.
