机载8毫米成像微波辐射计图像预处理

机载8毫米成像微波辐射计以中国海监飞机为平台,是国家863计划课题《航空遥感多传感器集成与应用技术系统》中的重要传感器之一,主要用于海洋溢油与海冰参量监测。微波辐射计图像处理技术为溢油体积、海冰厚度等信息特征的提取提供了依据,解决微波辐射计图像空间分辨率与温度分辨率相互制约问题,提高图像空间分辨率,并保持目标边缘清晰。对机载8毫米成像微波辐射计飞行实验数据的分析以及图像预处理方法作了详细介绍,并且获取到预期的航空遥感图像,对今后进一步的辐射计图像处理打下良好的基础。

Image Preprocessing of Airborne 8 mm Imaging Microwave Radiometer

Airborne 8 mm Imaging Microwave Radiometer aboard the Sea Supervise Plane of China, as one of the crucial sensors in "Airborne Multiple Sensors of Remote Sensing Integrated and Application Technology System" for a subject of national 863 project, was developed to observe the ocean oil spill and sea ice parameters mainly. Microwave Radiometer's image processing technology builds foundation for pick-up of much characteristic information such as the volume of oil spill and the thickness of sea ice, solves the contradiction between it's spatial resolvtion and temperature resolvtion, improves the image's spatial resolvtion and enhances it's edge. This paper provides analysis of experimental data and image preprocessing method with Airborne 8 mm Imaging. Microwave Radiometer, a obtain the anticipated image, and lay a good foundation to the further radiometer image processing in the future.
