摘要
为了提高雷达精度,舰船雷达一般都进行电波折射误差修正.由于无法精确测量大气剖面,故舰船雷达的电波折射修正精度较低.文中提出了一种基于微波辐射计大气遥感的电波折射实时修正新方法,它不仅具有全天候、实时性、机动性等特点,而且可以直接测量出电波传播路径上的大气附加时延积分,从而直接给出距离误差修正量.经与常用的2种电波折射修正方法比较,证明它的精度较高.
In order to raise the accuracy of radars, the warship-radar generally depends on the electricwave refractive correction of errors. Because the atmosphere section plane cannot be measured accurately, the electric-wave refractive of correction error is low in precision. The article presents a new method based on electric-wave refractive real-time correction of wave-radiometer atmosphere remote sensing. It is characterized not only by all weather condition, real-time, mobility and etc. , but also by directly measuring the atmospheric additional time-delay integral of electric wave transmission trails and giving error correction value of distance. As compared with two common methods, it has been proved that the new method is of higher accuracy.
