Abstract

The results of computer simulation of the lidar overlap functions obtained by the ray-tracing method for a transceiver optical system with four receiving apertures are presented. It is shown that when using a multi-element transceiver based on a combination of four receiving apertures of different diameters, the lidar sensing range from 5 to 3000 m can be obtained with a dynamic range of the lidar return not more than 10. A prototype of the Raman lidar based on the four-aperture transceiver is created. A comparison is made of the calculated values of the lidar returns for a given overlap function of the transceiver with the experimental values of the lidar Raman signals for a uniform atmosphere. The comparison results confirm the correctness of the calculation method and can be used as a criterion when adjustment of the transceiver.
