Study on Multi-pulse Laser Detection of Moving Target under Low SNR

This paper presents a multi-pulse laser radar system and target detection algorithm for motion target detection. In this paper, the system of multi pulse lidar is introduced firstly, and the detection performance of the target range is analyzed by combining the lidar equation. Then, aiming at the detection of the moving target, the influence of the target tangential velocity and the radial velocity on the multi-pulse echo accumulation is deduced, and the conditions of the effective accumulation of the multi-pulse echo are given. The constraints of the multi-pulse laser radar target detection system on the parameters such as the irradiation frequency and the emission pulse width are pointed out. Then, a multi-pulse laser target detection algorithm and its implementation steps are proposed, and the simulation results are given. The experimental results show the effectiveness of multi-pulse laser for target detection under low SNR.
