航空微波遥感海水盐度的研究

STUDY ON AIRCRAFT MICROWAVE REMOTE SENSING OF SEA-WATER SURFACE SALINITY

本文从海水复介电常数模型出发,分析计算了海水盐度对海水微波辐射亮度温度的影响,提出了遥感海水盐度的频率和入射角选择方案;据此设计并研制成高精度机载L波段微波辐射计系统,成功地进行了航空遥感海水盐度的试验,遥感盐度的精度达到千分之二。

Based on the models of the complex dielectric constant for sea-water' the in fluence of sea-water salinity on microwave radiation brighteness temperature of sea-water has been calculated, and te alternative of optimum frequency and incidence angle for remote sensing of sea-water salinity also has been proposed. According to the above, the airboen L-band microwave radiometer system with high prescision has been developed and used successfully to aircraft remote sensing of sea-water salinity. The accurancy of remote sensing salinity was 2‰.
