摘要
对地杂波散射特性的测量、分析与研究,对于提高电子战武器装备的抗干扰性能有着非常重要的意义。文中从此目的出发,简要介绍了地杂波特性测量原理及测试方法,并重点对平原、城市、谷地、丘陵等四种典型地貌特征的地杂波实测录取数据进行了比较、分析与研究。文中分析了地杂波RCS值与不同典型地貌特征的关系;结合不同地貌特征,分析了地杂波与不同测试频率之间的关系,以及地杂波与不同测试极化方式之间的关系,并从中得出了初步的结论。
The measurement, analysis and study of land clutter scattering characteristics is of great importance to the enhancement of the anti-interference performance of the weapon equipment in the electronic warfare. This paper introduces the principle of the measurement of land clutter characteristic and the test method with emphasis on the comparison, analysis and study of the admitted data about the four typical kinds of relief features： plain, city, valley and mound. The relationships of land clutter to different typical relief features, to different test frequencies and to different test polarization are analyzed, from which conclusions are drawn.
