对流层折射模型修正及对应的雷达求高公式

在研究了对流层大气折射经典模型的基本理论和方法之后，基于最小方差思想提出了一种新的性能优越的修正模型，并针对美国国家标准局中央无线电波传播实验室规定的指数关系的大气层参数数据，通过与经典模型相对比，验证了该修正模型的有效性和优越性。该模型为雷达目标测高、大气损耗计算等后续研究提供了更准确的理论依据。文中详细阐述了该对流层大气折射修正模型的建立过程，给出了基于此折射模型的修正的雷达目标求高公式。

Modification of Tropospheric Refraction Modes and Corresponding Radar Target Height Formula

Based on the idea of minimum variance,a new modified tropospheric refraction mode with better performance is proposed after studying on the basic theories and methods of several classical tropospheric refraction modes.The validity and superiority of the modified mode are verified by comparing with the classical modes using the data provided by the American National Bureau of Standards,Central Radio Propagation Laboratory(CRPL).The model provides accurate theory foundations for the succeeding research such as radar target height measurement and calculation of aerosphere loss.In this paper,the establishment of this modified tropospheric refraction mode is explained in detail,and the modified radar target height formula based on the refraction model is presented.
