| 摘 要： | 解释了角闪烁的两种物理概念及其计算方法;从数学上证明了远区角闪烁线偏差与雷达距离无关;以两个任意取向的电偶极子组成的典型目标为例,推导了考虑目标回波极化和接收天线极化时的角闪烁理论计算公式。理论分析和数值计算表明,在几何光学条件近似下,对线极化接收,相位梯度法与坡印亭矢量法完全等效。

| Abstract: | Two concepts of angular glint are explained as well as the computation methods.It is mathematically proved that angular glint linear deviations are independent of radar observational range in far-field region.A typical target consisting of two arbitrarily oriented electric dipoles is employed to formulate angular glint linear deviations when the polarizations of the scattered waves and the receiving antenna are considered,from which,the equivalence between phase gradient method and Poynting vector method is founded when the geometrical optics approximation is used,and the receiving antenna is linearly polarized. |
