外场雷达目标RCS极化特性测量方法

外场雷达目标RCS极化特性测量方法

内容简介：在外场动态RCS测量中,普遍采用自由空间标准金属球对测量系统进行标校,但这种方法只能完成对测量系统同极化的标校,而不能对交叉极化通道进行标校。在对各种标准目标的RCS极化矩阵进行详细分析的基础上,提出了一种新的标校方法,该方法能同时对测量系统的同极化和正交极化通道进行校准。

Abstract：A standard metal sphere in free space is often used to calibrate the radar measurement system in outer-field dynamic radar cross section（RCS） measurement,this method can only perform the copolarization calibration to the measurement system,but can not perform the calibration to the cross polarization channel.Based on analyzing the RCS polarization matrix of all kinds of standard objects in detail,this paper presents a new calibration method,this method can perform the calibration to the copolarization and cross polarization channels of measurement system at the same time.
