简单面目标的雷达散射截面及其物理相似性
RADAR CROSS-SECTION OF SIMPLY FACE-SHAPED TARGETS AND THEIR PHYSICAL SIMILARITY
-
摘要: 雷达目标的散射截面值随目标的形状、大小、电磁波的波长和传播方向而变。本文给出了简单外形导电面目标的雷达散射截面随这些参量改变的一般表示式。利用这个表示式,可从不满足尺寸或波长缩比条件的模型测试值推算原型目标的雷达散射截面值。Abstract: Radar cross-section of targets varies with their configurations, dimensions, wavelength and radiation direction of waves. In this paper, a general representation for the radar cross-section of simply face-shaped scatterer with variance in these parameters is given. With this representation, the radar cross-section of prototype of this scatterer can be evaluated by means of model-testings, even though the scaling relations between the prototype and the models are not satisfied.
