某相参雷达散射截面积(RCS)动态测量雷达可采用脉冲压缩技术,其接收机信号输出幅度、相位校准需要有标准信号源,目前国内能够买到的国外综合信号源,远不能满足校准要求.文中采用等效自校准原理,研制了RCS动态测量雷达幅度、相位校准系统,解决了采用脉冲压缩技术的RCS动态测量雷达的幅度、相位校准问题.

Pulse-compression technology can be used in radar cross section(RCS)dynamic measurement.Calibration of output amplitude and phase needs a standard signal source.Currently,the foreign synthesized signal sources bought from domestic markets do not satisfy the requirements of calibration.Thus,utilizing the equivalent self-calibrated principle,a calibration system of amplitude and phase required by RCS dynamic radar is developed.Thus,it resolved the problem of calibration of amplitude and phase.
