Abstract: The meter-wave band radar (MBR) is characterized by big mass and the large-area antenna which must be packed up into several units for transportation. Its mobility design is the difficult problem of the radar engineering, especially the fast erecting and dismantling of the antenna vehicle. Design of a MBR antenna vehicle system is introduced in this paper, such as integrated design of the system, reasonable division and proper folding of the antenna array, the design of the automatic erecting and dismantling mechanism including the overturning, folding, locking mechanism etc. Simulation and optimization design are carried out by MSC.ADAMS. The test shows that the mobility of the radar meets the requirement. This design can be used as a reference for the mobility design of the similar large radar vehicle.
