摘要
介绍了激光主动成像技术的原理、特点和性能指标,通过理论计算和实验,研究了激光主动成像的距离和识别能力,并对其分辨率、激光发散角、焦距视场等参数进行了定量的分析.根据理论研究和实验验证推算的结果,证明了分析的正确性.要提高成像距离,减小发散角比增大激光功率的作用要更明显,在发散角小于4 mrad时可以实现对10 km的2 m目标进行成像识别.
The laser active imaging technology＇ s principle, characteristics and performance index are de- scribed. Through the theoretical calculation and the experiment, the laser active imaging distance and the recog- nition capability are studied. The parameters such as resolution, laser divergence angle, focal length and field of view are quantitatively analyzed. According to the results of theoretical study and experimental verification, the correctness of the analysis is proved. To increase imaging distance, the effect of reducing the divergence angle is more obvious than that of enhancing laser power. When the divergence angle is less than 4 mrad, the image i- dentification of the 2 m target at 10 km can be achieved.
