| 摘 要： | 机载合成孔径雷达中,天线稳定平台用于隔离载机的姿态变化和机械振动对天线指向的影响,并通过伺服系统控制平台支承轴的转动稳定波束指向。仿真了两种不同天线伺服配置对点目标成像的影响,分析了两种伺服方法的实现原理。通过比较两种伺服方法的特点及优劣,对不同机载SAR成像条件下对天线稳定平台控制方式的选择提供参考。

| Abstract: | In airborne synthetic aperture radar(SAR),antenna stabilization platform is used to isolate antenna pointing,which is stabilized through controlling the platform axis' rotation,from the vehicle's varying attitude and dynamical vibration.The effects of two different antenna configurations on imaging point targets are simulated,the realization principles of these are presented.According to comparison between the two configurations' respective advantages and disadvantages,some reference can be provided about how to choose the control mode over the antenna stabilization platform under different airborne SAR imagery conditions. |
