簡單面目標的雷達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: 雷達目標的散射截面值隨目標的形狀、大小、電磁波的波長和傳播方向而變。本文給出了簡單外形導電面目標的雷達散射截面隨這些參量改變的一般表示式。利用這個表示式,可從不滿足尺寸或波長縮比條件的模型測試值推算原型目標的雷達散射截面值。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.
