XCN 3D is the first mountain geophysical exploration project using WiNG node.In order to master the performance characteristics of WiNG instrument's Pathfinder,point-to-point and other QC methods used in the mountain,and improve the production efficiency of the instrument,representative test points were first selected in the work area,Pathfinder,point-to-point and other QC methods were tested with small array,and the prelim-inary WiNG mountain QC method was summarized.Then,in the QC process of large-scale WiNG of the project,constantly summarize and correct,find out the characteristics of the use of the QC method of large-scale WiNG in the mountain,so as to sum up a set of efficient QC method suitable for the WiNG in the south mountain,to a-chieve the purpose of speeding up the production of mountain WiNG instruments,improving efficiency and im-proving quality.
