Abstract
It is very difficult for both detectors and data acquisition systems to cope with the enormous signal dynamic range of incoherent lidar systems. The high power of the near-range atmosphere-backscattered radiation may cause serious problems to detectors. If the detector can endure the high power, the dynamic range of the output electric signal still remains a problem. To solve the problems, this paper suggests using a multibeam transmitter instead of a single-beam transmitter. With a multibeam transmitter a significant reduction of the signal dynamic range can always be achieved simultaneously with good near-range coverage even under different atmospheric conditions. Numerical simulations for a differential absorption lidar (DIAL) system measuring ozone in the lower troposphere below 3 km show the advantage of using a three-beam transmitter rather than a single-beam transmitter.
