A straightforward method is presented for the determination of the geometric form factor in Raman–Mie lidar by using elastic backscatter signal from different altitudes and derived particle backscatter coefficients. The theory is briefly described. The error of this method is discussed and a comparison with the method proposed by Wandinger and Ansmann indicates the improved accuracy of the new method...
The telescope is a key optical component which largely affects the signal intensity in coherent Doppler Lidar. In the paper the normalized signal to noise ratio(SNR) as a function of range z and diameter D of the telescope is investigated for pulsed coherent wind lidar, then the telescope aperture requirement for 300km orbit is calculated and presented. After that the initial structure parameters...
