摘要
为满足目标宽带雷达散射截面积(WB-RCS)理论研究的实验验证需要,绕过脉冲体制,提出了一套宽带扫频自动测量系统。介绍了该系统硬件、软件设计,特别是给出了一整套硬件、软件对消方案,大大降低了系统测试对信噪比的要求。经实际测试,满足设计要求,为指导理论深入研究提供了有力的实验支持。
To validate the theory study conclusions about target's Wideband RCS,an auto-measurement system,based on frequency scanning mode,but not pulse mode,is designed. The design of the hardware and software are elaborated. In especial,a self-designed scheme to eliminate white-noise,through both hardware and software,is given. It greatly reduces the minimum limit of SNR,which is needed to test correctly. Through testing,it's verified this system is able to give a powerful test support to the study.
