摘　　要：根据雷达目标雷达散射截面(RCS)测量原理结合测试试验,建立了一套宽带扫频RCS自动测量系统。通过系统硬件、软件的合理设计,实现了三维宽带扫频RCS测试的自动化。在暗室环境条件下,通过背景噪声抑制技术、低散射支架技术、软件时域门技术和采用高精度金属球作为定标球等方法,显著提高了系统的测量精度,其扩展不确定度达到了0.92dB。经实际测试,满足设计要求,能够满足目标宽带RCS试验测试和理论研究的实验验证需要。According to the measurement principle of the RCS and combined with the test in anechoic chamber,a set of broadband swept frequency RCS automatic measurement system is built.Base on the design of the hardware and software elaborated,the 3d broadband swept frequency RCS automation is implemented.The survey precision of the system is increased obviously by the technology of eliminating background noise,low scattering supporting structure,software time domain gate and high degree of accuracy calibration metal sphere.The expanded uncertainly is 0.92dB.Through testing,it＇s verified this system is able to give a powerful test support to the targets broadband RCS testing and the study.
