phased.CardioidAntennaElement
心脏化天线元件
描述
TheCardioidAntennaElement
System Object™模型的天线与Cardioid Response。有心细胞天线通常用于方向发现。可以通过将两个各向同性辐射器放在阵列中,相距四分之一波长和相位90°来实现心脏响应。心形模式的默认旋转在180°方位角和0°海拔时为无效。0°方位角和0°升高被认为是天线的主要响应轴。当放置在线性或矩形阵列中时,主响应轴与阵列正常对齐。
To compute the response of the antenna element for specified directions:

Note
对象第一次执行对象执行初始化。此初始化锁定不可否认properties和input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the发布
