Reflective Tomography Lidar Image Reconstruction for Long Distance Non-Cooperative Target

In the long-distance space target detection, technique of laser reflection tomography (LRT) shows great power and attracts more attention for further study real use. However, targets are often non-cooperative, normally a 360° complete view projections cannot be obtained. Therefore, this article firstly introduces an improved LRT system design with advanced equipment non-cooperative detection to ensure high quality lidar beam projection data. Then, image reconstruction is proposed focused on method utilizing total variation (TV) minimization approach based sparse algebraic (ART) model, in order reconstruct or incomplete projections. At last, comparative experiments performed validate advantages system. both near far field experiments, effectiveness superiority verified different types data through comparison typical methods.
