In order to study the impact of geometry of the transceiver in the non-line-of-sight system working at the wavelength of 1.06μm,based on a single-scatter atmospheric propagation model,the impact of the field-of-view(FOV)of the transceiver,pitching angle and transmitting distance on the received signal power and path loss was studied by means of numerical calculation.It is shown that a larger FOV may significantly enhance the detected laser power,while the increase of transmitter beam divergence does not make any difference.It is also indicated that decreasing either the apex angle of the transmitter or receiver makes the detection of the weak scattering signal more difficult while other parameters remain the same.It is shown that decreasing the apex angle of the transmitter appropriately helps the signal detection for a certain scattering angle and transmitting distance.These results are valuable in system design.
