As the overhead ground wire of the ultra-high-voltage transmission line (UHV TL) is connected to the steel tower with arrester,the wire and the tower is open-loop,the single tower can be seen as a unit of antenna,the simplified calculation method based on the single tower s reradiation field and the array-coefficient is provided.
特高压架空输电线路的架空地线通过避雷器与杆塔连接,杆塔与地线没有构成闭环,单个杆塔可看作独立的天线元考虑,据此提出了用单个杆塔的二次辐射场推导出杆塔成列影响的计算方法以简化特高压输电线路的二次辐射场。
Once more,the relationship between far-field and near-field is deduced by regarding image of the target as secondary radiation source.
根据ISAR成像中目标反射率空间分布特性不随测试状态改变,建立了多散射中心模型;针对隐身目标自身高度较小、在竖直面上满足远场条件的特点,将入射球面波等效为柱面波照射;以目标像作为二次辐射源,导出了远近场之间的依赖关系式;利用目标全角域近场散射信息进行外推,获得了远场条件下各个角度的RCS值。
