| 英文摘要 | In recent years, imaging-based lidar techniques have been widely studied and employed in atmospheric remote sensing, while different theoretical descriptions are introduced for lidar systems with specific optical configurations and a universal guideline for optimizing system performance is still lacking. In this work, a generalized theoretical model (GTM), suitable for various imaging-based atmospheric lidar techniques, has been concepted and established for describing the relationship between the system performances and optical configurations, where a few factors have been derived and defined. Comprehensive simulation studies based on the GTM have demonstrated that the range resolution, the blind range, the minimum scattering angle of the lidar signal and the tilt angle of the image sensor are strongly dependent on the focal length of the receiving lens (or telescope) and the transmitter-receiver separation, etc. In particular, the range resolution is proportional to the product between the focal length and the separation. Besides, the intensity factor, the signal-to-background ratio (SBR) factor, as well as the signal-to-noise ratio (SNR) factor, which are immune from atmospheric conditions, etc., have been proposed and deduced to quantify the performances of imaging-based lidar system with different optical configurations. It has been found out that the SBR factor, an indicator for the requirement on the dynamic range of the image sensor, is inversely proportional to the separation. Meanwhile, the intensity factor and the SNR factor are related to the separation, the focal length as well as the aperture of the receiving lens, etc. The GTM provides valuable insight for understanding the principle of the imaging-based atmospheric lidar technique as well as a general guideline for system design and implementation. |
