Satellite-to-satellite Lidar Imaging Using Reflective Tomography
Taking satellite-to-satellite lidar imaging as application background, an imaging processing method based on chirped pulse for reflective tomography lidar is presented. In this method, high precision image reconstruction is obtained by extracting projection data of different observation angle and using CBP algorithm. The condition of satellite-to-satellite lidar reflective tomography imaging is analyzed, including imaging resolution, working modes and imaging time. The results show that, the mode of accompanying satellite detecting in the same orbit plan meet the requirement of multiple angle detecting for lidar reflective tomography imaging.0.1 meter spacial resolution can be achieved while the range of detecting angle is larger than 60 degree, and the larger the range of angle, the higher the resolution is. The imaging time depends on the satellite orbit radius and the range between two satellites. Imaging experiment validates the feasibility and effectiveness of the presented method.
