Abstract: With the increasing of requirement to radar mobility,higher and higher requirements to specifications such as radar antenna vehicle assemble/disassemble and etc.are required.Because of its unique advantage of high control power,Hydraulic system is widely used in the control of mobile radar vehicle assemble/disassemble.In this paper,the leveling control tactics of radar vehicle hydraulic control system are presented,and the implementation of automatic flow is described.Finally,some suggestions on practical issues occurred in engineering practice are provided.
