The Patriot missile, unlike other human-guided infrared missiles, is wholly dependent upon ground-based radar to identify and track targets that may be traveling at three to five times the speed of sound. The ability to automatically detect and launch is a unique feature for targets that are likely to be far outside visible range and at high velocity. For this reason it is critical that the radar set be functioning properly, as it is fundamental for mission success.
The Patriot Missile Phased Array Radar Set supports up to sixteen missile launching stations and is mounted on a semi-trailer and towed by an expanded mobility tactical truck. It is monitored and controlled by an Engagement Control Station via a radar and weapon control interface unit. The Radar Set performs very low to very high altitude surveillance, target detection, target classification, target identification, target track, missile track, missile guidance and ECCM functions.
In 2007, Cocoon was contracted by the Department of the Army to design and develop a dehumidification system for deployment to operations in the Far East. Requirements included no major modifications to the existing equipment; easy connection, disconnection and handling; EMP/RDI protection not to be validated; the system be developed based on existing production methods, materials, standards and technology (COTS); and capability of tactical deployment on the vehicles, if necessary.
Based on a similar system developed for the Royal Netherlands Air Force (RNLAF), Cocoon and its partner Munters, provided a system of portable dry air dehumidification units. Each is connected to the Radar Set using 25 feet of easily-connectable 5” flexible ductwork with all system components packaged within a rolling cart.
As experienced from previous application, the result has been a significant reduction in overall maintenance requirements as well as system start-up time. Part of a more comprehensive corrosion prevention program, Cocoon is also in the process of developing a supplemental cover system to provide additional protection from detrimental environmental factors.
