Path loss is an important parameter to evaluate the transmission performance of the system. Based on the non-line-of-sight non-coplanar ultraviolet single-scatter transmission model, the traversing tiny unit method (TTUM) is used to simulate the single-scatter path loss of wireless ultraviolet communication in mobile scenes, and the influence of the geometric parameters of the transceiver and the relative position change of the transceiver node on the path loss of the system is analyzed. The results show that path loss increases with the increase of the moving distance of the receiver in the other directions except 180°; with the increase of transceiver elevation angle, path loss increases, and the effect of transmitter elevation angle on path loss is more significant; when the field of view angle is large, the change of beam divergence angle has little effect on path loss, and change of field of view angle has a more obvious effect on path loss in non-coplanar case and large moving distance, while it has little effect in other cases.
