摘　　要：机载SAR天线及转台结构设计中很关键的一点就是天线布局方案的设计。由于天线罩的包络空间有限并且不规则,使得天线布局方案设计复杂,不易优化。针对某机载SAR系统给出了三种天线布局设计方案,并使用Inventor软件的驱动约束功能对天线布局方案进行了简单有效的运动仿真分析,给出了优化设计建议。布局方案及设计方法可以为同类机载SAR天线布局方案设计提供参考。One of the key points in the structure design of airborne SAR antenna and gyro - stabilized platform is the antenna layout design, which is complicated and difficult to be optimized because of the irregular shape and space envelope of radome. This paper gave three antenna layout designs for an airborne SAR, made simple kinematics simulation analysis for the antenna using the inventor software＇s assembly chaining driver function, and obtained the optimization result of layout design at last. As a reference, the antenna layout designs and methods can be used for the similar layout designs.
