近年来，弹载 SAR 制导技术已成为 SAR 技术应用的又一重要方面。在体积有限制的战术导弹应用中，为了消除弹体姿态变化对目标测量的影响，往往采用捷联稳定平台来实现天线稳定。阐述了两轴天线稳定平台的设计思路及结构框架，根据捷联式天线平台的结构特点及稳定平台工作原理，应用坐标变换方法，建立了两轴天线平台的运动学模型。根据不同工作模式对天线尺寸的要求，设计了随工作模式实时切换的同轴双天线，并依据建立的大天线坐标系推导出小天线坐标变换关系。

For volume-limited tactical missile,the strapdown stabilization platform is applied to stabilize the antenna of a small size SAR seeker.In this paper,a dual-axis antenna stabilization platform is designed according to the operation attitude change of missile-borne SAR and the limited volume.Based on the struc-ture characteristics and the working principle of strapdown antenna stabilization platform,the kinematics model of the dual-axis antenna stabilization platform is established by use of the method of coordinate trans-formation.According to the antenna size requirements at different work modes,the coaxial double antennas that can be switched over in real time with operation mode are designed.At last,from the coordinate of the large antenna system,the small antenna coordinate transformation is deduced.
