本文报导了一些典型目标和真弹头,如20毫米弹头,MI—105毫米炮掸和一种带尾翼的金属圆柱弹的雷达截面积(RCS)的分析和实验结果。用来取得所示数值结果的各种分析方法包括几何和物理光学法、衍射几何理论法和矩量法。文中介绍了为获得在1,10和35千兆赫上的实验结果所采用的一些测量技术,并从可靠性和可重复性角度出发讨论了实验步骤和结果。还对实验的和分析的这两种型式的结果进行了讨论和比较。
This article reports the analysis and experimental results of some typical targets and true-to-air warheads such as the 20-mm warhead, the MI-105-mm gun duster and the RCS with a tail-mounted metal cylindrical projectile. Various analytical methods used to achieve the numerical results shown include geometry and physical optics, diffraction geometry theory, and moment method. The article presents some of the measurement techniques used to obtain experimental results at 1, 10, and 35 GHz, and discusses the experimental steps and results from the point of view of reliability and repeatability. The results of the two types of experiments and analyzes were also discussed and compared.
