摘要
针对两维阵列数字单脉冲测角,提出一种改进的方法,首先完成一组无等效孔径变化效应的偏差测量,然后通过高阶多项式拟合进一步实现方位和俯仰联合测角,以改善测角误差性能。通过分析无等效孔径变化效应偏差角与方位和俯仰差之间的关系,得到了相应的测角方法;并通过仿真验证了该方法是有效的。
An improved digital mono-pulse angle estimation method for two-dimensional antenna array is presented.Deviations immune to the effect of equivalent antenna aperture variation at different direction are firstly measured.Then the azimuth and elevation are jointly measured through high order polynomial fitting to improve the performance of measurement error.Relation between the deviations and the azimuth and elevation is analyzed,which results in the corresponding estimation method.Simulation result shows that the proposed method is valid.
