This paper aims at the application requirements of target localization in specific environments, a method based on single scattering of polarized ultraviolet light to achieve non-line-of-sight target localization is proposed. In this paper, the target positioning is completed by combining with the obtained target azimuth angle and distance. Firstly, in this paper, based on the non-coplanar single scattering channel model of a spherical coordinate system, combining with the transmission characteristic of atmospheric scattering of polarized ultraviolet light, the single scattering model of polarized ultraviolet light is established for the non-line-of-sight targets which are not at the same height. The polarization scattering transmission characteristics of ultraviolet light and the variation of the radiation intensity were analyzed by the method of matrix optics. Thus a relationship between the received light intensity and the azimuth angle and the distance between transmitter and receiver was established. Then, matlab software is used to simulate and analyze the effect of the distance between transmitter and receiver on the received light intensity under the condition of the maximum receiving light intensity during sunny and smog days. Finally, the effect of the elevation error of the receiver and the transmitter on target positioning is simulated and analyzed. At the distance between transmitter and receiver of 400m, the distance measurement error is 20.6m on sunny days and 26m on smog days when the transmitter and receiver elevation angle deviates 3° (the preset transmit elevation angle is 35° and receive elevation angle is 25°). In addition, the background light affects determination of the azimuth angle but has a small impact on the ranging. In order to achieve accurate target positioning, this paper proposes effective improvement measures for the above possible errors.
