摘要
大气环境对电磁波的吸收衰减作用使雷达的作用距离减小,大气异常折射现象使雷达的作用距离增大或减小.为此重点研究了气象要素特别是异常折射对雷达作用距离的影响,从分析异常折射产生的原因和规律入手,提出了气象要素的观测和雷达作用距离的预测方法.该方法对雷达在航海及军事上的应用具有重要意义.
Atmosphere absorbs the electromagnetic wave so that the radar detection distance be reduced, and the atmospheric unusual refraction changes the radar detection distance too. This paper mainly studied the influence of weather factor especially of unusual refraction on radar detection distance, based on the analysis of the causation and rule of unusual refraction, put forward the method of observing weather factor and forecasting radar detection distance.
