Abstract

Range-gated technique is useful for improving the accuracy of 3D target attitude measurements. The 3D super-resolution range-gated imaging technique and 3D inversion algorithm are introduced. In this paper, the characteristics of high-speed moving targets are analyzed. Nanosecond sensor gate is selected to capture instantaneous images to eliminate the effect of target movement. Based on this design, a dual-camera range-gated imaging measurement system is analyzed. Through imaging experiments on different targets, the system is feasible and for a target 20m away, the root-mean-square error of the measurement is 0.69cm. At the same time, the possible errors caused by the introduction of dual camera system and a reasonable solution is analyzed. The results show that the proposed system can effectively measure the 3D attitude information of high-speed moving targets, improve the ranging accuracy, meet the requirements of real-time 3D imaging, and provide a basis for subsequent data processing and ranging performance improvement.
