| Abstract: | For differential absorption lidar(DIAL) system,two signal processing techniques,signal averaging and Kalman filter,are studied,and numerical simulation results are obtained.These results show that the concentration-length(CL) of target gas can be estimated well and the detection accuracy can be improved greatly after using signal averaging or Kalman filter.Performance of signal averaging is compared with Kalman filer using simulated data. |
