单点频与宽带扫频测试目标RCS的比较

Comparison between the Continuous Wave and Linear Frequency Mode of RCS Measurement

通过对RCS测试方法中的单点频(连续波)与宽带扫频测试方法进行研究,得出宽带扫频技术在RCS测试过程中的重要性。从两种测试方法的不同测量步骤和测量原理,并结合测量结果进行分析,可以看到点频测量方法所得的结果不能全面反映目标的散射特性,并且分辨率和精度受到限制。而利用宽带扫频技术对目标的RCS特性进行分析,能够全面反映目标的散射特性,且可以提高测量精度和目标分辨率,进而指出了其广泛的应用前景。

Two methods of RCS measurement, which is under the Continuous Wave（CW） and linear frequency mode,is studied in this paper,and the significance of the linear frequency mode is summarized. Combining with the result and making analysis from the different measurement process and theory,we can find that the measurement result of the CW mode does not make a full reflection of the objectts scatter characteristics. At the same time,the resolving power and measurement precision is restricted. But the linear frequency mode can make an opposite result,and its colorful application foreground is put forward.
