大范围多尺度雷达仿真数据的生成算法

针对航海模拟器中由单张海图生成的小范围雷达仿真数据引起的雷达仿真图像不连续和跳跃问题，提出一种生成大范围雷达仿真数据的方法.首先, 筛选并确定海图库内需要使用的S-57标准电子海图，对这些比例尺不同的海图分别生成雷达仿真数据；然后，根据所需雷达数据范围，采用裁剪、排序、去重、合并、拼接等算法操作，生成大范围连续的多尺度雷达仿真数据.以宁波港附近水域为例，实验证明，该方法生成的雷达仿真数据高效准确，能够满足航海模拟器的实际需要.
In order to solve the discontinuity and saltation of radar simulation image in maritime simulator resulted from only reading a small range of radar simulation data generated from single chart, a method was proposed to generate a wide range of radar simulation data based on multiscale chart data. Firstly, S-57 standard electronic charts to be used were filtrated in chart library to produce radar simulation data for those different scale charts. Then, by using the algorithms operating such as clipping, sorting, deletion, combination as well as matching, a wide range of continuous multiscale radar simulation data were generated. Taking the water area around Ningbo Port as an example, experimental results prove that the radar simulation data generated by this method have high accuracy, which can meet the practical requirements of maritime simulator.
