采用频率步进连续波体制进行RCS测试是一种新技术,本文具体研究了频率步进连续波测试系统的信号处理模型,分别对回波数据在IFFT处理中的补零点数、数据截断宽度和窗函数选取等方面进行深入分析,最终通过系统地实验验证,表明信号处理工具的有效应用,使得频率步进连续波RCS测试技术具备良好的测试精度和较宽频段的目标特性信息。
It is a new technique to test the RCS by using the frequency stepping CW system. In this paper, the signal processing model of the frequency stepping continuous wave test system is studied in detail. The zero points, the truncation width and the truncation width of the echo data in the IFFT process Window function selection and other aspects of the in-depth analysis, and finally through systematic experimental verification that the effective application of signal processing tools, making the frequency step-by-step continuous wave RCS test technology with good test accuracy and wide band of target characteristics of information.
