Description

Phased array radar skeleton Technical Field The utility model relates to the technical field of radar frameworks, in particular to a phased array radar framework. Background The phased array radar skeleton is a structure for providing mechanical support to each component of the phased array radar antenna to ensure accurate and stable relative positions of each component of the phased array radar antenna in space, so that the antenna head can work normally. Among the prior art, phased array radar skeleton often forms by many connecting rods welding, and phased array radar skeleton is installed in outdoor environment often, and then leads to the easy fracture of appearing in the welded part on the phased array radar skeleton for maintenance personnel need regularly inspect the phased array radar skeleton, in order to in time weld the welded part of fracture again. Because the step of welding is comparatively loaded down with trivial details, and welding operation need use professional welding equipment, and then is unfavorable for improving maintainer's convenience of maintaining phased array radar skeleton. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the phased array radar framework provided by the utility model can improve the convenience of maintenance personnel for maintaining the phased array radar framework.
