利用自行设计、制作的扫描昆虫雷达数据分析系统,对雷达数据进行图像绘制,通过参数设置统计指定空间范围内昆虫回波点的方位、高度、距离、密度等关键生物学参数,以实现昆虫活动的准确预测和预报。通过利用R统计平台与生物学辅助方法相结合开发建立分析平台。系统在实现雷达数据读取、信号格式转换、回波数据统计等功能的同时,在技术上实现了对重建迁飞害虫空间飞行动态的支持,将填补原有程序中没有数据分析功能的空白。
The data collected by the scanning entomological radar are analyzed and transferred to images by self-designed analysis system. To achieve the accurate prediction of insect activities, some key biological parameters of insects, such as the position, height, distance, density of the echo point within the designated space, are investigated by setting statistical parameters. The analysis platform are developed through the combination of R statistical platform and biological assisted methods. The system realized functions include radar-metadata accessing, signal transformation, echo-data Statistics, and so on. Simultaneously, the key technique of reconstructing spatial movement model of migrant insects are carried out. It will supply a gap of no data analysis in former systems.
