摘　　要：对于舰载雷达截面(RCS)测量雷达,由于舰船摇摆,天线极化方向发生变化影响目标的极化特性测量。传统补偿方式是将整个雷达安装于纵横摇稳定平台上,考虑载重及风阻力影响,稳定平台不仅笨重而且精度受限。提出了一种馈源扭极化的方式来进行极化稳定,该方式只需增加一套扭极化装置即可实现极化的稳定,不仅设备量小而且不影响设备的安装。For the shipborne radar cross section(RCS)measurement radar,the change of antenna polarization direction because of ship sways will affect the measurement of target polarization characteristics.The traditional compensation way is to put the whole radar on the stabilized platform.The stabilized platform is not only heavy but also has limited accuracy due to the influence of load and wind resistance.In this papar,a method of polarization compensation by rotating the feed polarization is proposed to stabilize the polarization,which can be realized only by adding a set of rotating control device,and the equipment is little as well as no influence on installing.
