本文综述了激光雷达的理论和技术,把微波雷达和光雷达作了比较,讨论了整个电磁波谱内的大气传播性能和距离方程。给出了非相参探测系统(激光测距仪和高度表)及相参探测系统(卫星跟踪装置和晴空气象雷达)的具体实例。
This paper reviews the theory and techniques of laser radar, compares the microwave radar with the radar, and discusses the atmospheric propagation properties and distance equations over the entire electromagnetic spectrum. Specific examples of non-coherent detection systems (laser range finders and altimeters) and coherent detection systems (satellite tracking devices and clear-air weather radars) are given.
