提出了张力桁架天线的概念。结果表明，抛物面反射面可以由三维整体索格系统构成，该系统可称为张拉桁架。张力桁架天线由三角形面索桁架、射频反射面和支撑结构组成，该支撑结构提供索格的支撑和预张力。天线的主要特点是它的形状实际上是由几何数量决定的，比如电缆成员的长度和排列。由于这一特点，天线表面的调整可以直接通过改变构成表面的电缆构件的长度来完成
The concept of the tension truss antenna is proposed. It is shown that a parabolic reflector surface can be formed by a three-dimensional integrated cable lattice system that can be called a tension truss. The tension truss antenna consists of a triangular-faceted cable truss, the rf reflector surface, and a supporting structure which provides support as well as pretension of the cable lattice. The primary feature of the antenna is that its shape is virtually determined by geometric quantities such as the lengths and arrangement of cable members. Because of this feature, the adjustment of antenna surface can be done directly by changing lengths of cable members which form the surface
