Scope

This document stipulates the basic requirements for lightning protection of radar stations, including the requirements for radar station buildings, radar antenna platforms, radar machine rooms, communication transmission systems, power distribution systems, other ancillary devices, and the maintenance and management of lightning protection devices for radar stations. This document applies to the design, construction, and maintenance of lightning protection devices for meteorological radar stations, air traffic control surveillance radar stations, and scene surveillance radar stations. Other types of radar stations may refer to this document for implementation. Note 1: In this document, "buildings" generally refer to buildings (structures). Note 2: Typical radars applicable to meteorological radar stations include weather radars and wind profiler radars; typical radars applicable to air traffic control surveillance radar stations include primary air traffic control surveillance radars and secondary air traffic control surveillance radars; and typical radars applicable to scene surveillance radar stations include scene surveillance radars.
