摘要
文章回顾了近40a来海水盐度遥感技术的发展，包括遥感原理、反演算法、影响因素、航空实验、卫星遥感等方面取得的进展。指出，以1．400～1．427GHz为海水盐度遥感的首选波段，采用L波段（1．4GHz）和S波段（2．65 GHz）组成的双波段、双极化、较大入射角的天线工作方式有助于提高盐度遥感的精度。影响盐度遥感的三个主要因素是：太空、海面和大气。目前，航空盐度遥感的反演精度已经达到了0．3psu。
Advances on the ocean salinity remote sensing, including theory, retrieval and correcting algorithm, influencing factor, airborne experiments and satellite developments, point out that, the 1. 400- 1. 427GHz is the best microwave band for salinity remote sensing. Adopting dual-band （L-band and S-band）, perpendicularity-polarization and larger incidence as the working of the antenna are of benefit to improve the precision of salinity remote sensing. Three influencing factors of remote sensing of salinity are outer space, sea surface and atmosphere. At present, aviation remote sensing of salinity has arrived at 0.3psu.
