The dynamic equation of the rigid-flexible coupling nonlinear system is derived based on Lagrange Equation by adopting centralized parameters method. And we make a numerical simulation of the antenna's supporting beam's vibration when the satellite is rotated a little angle surrounding the Z axis. 本文首先采用集中参数法,利用拉格朗日方程推导了卫星&天线系统的刚柔耦合动力学方程,并对该方程进行了数值仿真,获得了系统的调姿响应和天线结构的模态。
By studying on the model of Antenna Pattern, this paper simulated the single and sum-difference beam pattern of phased-array radar which works on single pulse angle measuring. 然后介绍了相控阵雷达天线方向图模型,仿真了测角体制相控阵雷达天线单波束以及和差波束方向图。
