机载激光测深系统中海面波浪影响的改正

Correction of Sea Wave for Airborne Laser Bathymetry

针对研制的新型机载激光测深系统的海上飞行试验数据,进行预处理、信息提取、数据同步和坐标转换后,开展波浪改正研究.对海底高程的GPS高程信息无波浪改正、GPS高程信息改正飞机航高变化计算波浪和加速度信息改正飞机航高变化计算波浪三种技术进行了分析.数据处理结果表明,采用加速度信息改正飞机航高变化计算得到的波浪信息的方法,结果较好,可满足研制的机载激光测深系统的要求.

The correction of sea wave using the data measured by a new developed airborne laser bathymetry is presented. Three different sea wave correction methods of no correction using GPS, using height of data from GPS,and using acceleration data from GPS are analyzed and compared. Results show that the method using acceleration data from GPS can give better results,and are fulfilled for the new developed airborne laser bathymetry.
