相控阵雷达比相测角法研究

Research on Angle Measurement Method for Phase Comparison of Phased Array Radar

在抛物面天线体制跟踪雷达中,采用和差通道比幅法来测量目标角度,在相控阵天线体制中,目前多使用和差通道比幅法来测角。介绍了一种比相测角的方法,用于相控阵雷达的目标角度测量,此方法优点是测角精度高、测角速度快、测角范围大。

In parabolic antenna radar systems,the sum and difference channel amplitude comparison method is used to measure angle.In phased array radar systems,the sum and difference channel amplitude comparison method is still used to measure angle.A method of phase comparison angle measurement for phased array radar target angle measurement is introduced.The advantages of the method are high angle measurement accuracy,fast angle measurement speed,and wide angle measurement range.
