自然闪电是一种全球现象。静止闪电测绘仪探测涉及全球范围内自然闪电发生的时间、地点和强度分布。这一飞行任务的功能和性能与其他对地光学遥感器有很大差别,因此仪器的设计必须完全建立在新的理论和技术基础上。分析自然闪电的光谱特性、时间特性和空间特性,了解空间探测闪电环境,以及研究自然闪电和其探测环境间的相互作用,对这种仪器的设计优化至关重要。为此,研讨了静止闪电测绘仪的设计特点,包括闪电信号的最大化、强背景减除和星上数据处理等。
Natural lightning is a global phenomenon. Stationary lightning plotter detects the distribution of time, place and intensity of natural lightning occurring worldwide. The function and performance of this mission are very different from other optical remote sensors on the ground, so the design of the instrument must be based entirely on new theories and technologies. Analyzing the spectral characteristics, temporal characteristics, and spatial characteristics of natural lightning, understanding the lightning environment in space, and studying the interaction between natural lightning and its detection environment are crucial to the design optimization of such instruments. Therefore, the design features of static lightning plotter are discussed, including the maximization of lightning signals, strong background subtraction and on-board data processing.
