摘要
基于一维干涉仪测向原理,建立包含辐射源俯仰角的测向模型,研究辐射源俯仰角引起的测向误差,仿真验证测向模型的合理性;结合安装平台的伺服系统,在不同平台俯仰角下测量同一辐射源的方位值,详细推导辐射源俯仰角和修正方位角的数学方程;在辐射源俯仰角基础上引入相位误差,并通过仿真发现修正后的测向误差得到明显改善,进而说明方法的正确性。
Based on the direction finding principle of a one-dimensional interferometer,a direction finding model including the pitch angle of the radiation source is established.The direction finding errors caused by the pitch angle of the radiation source are studied,and the reasonableness of the direction finding model is verified through simulation.By combining the servo system of the installation platform,the azimuth value of the same radiation source is measured at different platform pitch angles.The mathematical equations of elevation angle and corrected azimuth angle are derived in detail.Phase errors are introduced based on the radiation source pitch angle,and simulations show that the corrected direction finding errors are significantly improved,thus confirming the correctness of the method.
