Investigating the impact of water quality, target characteristics, and target distance on underwater laser detection is crucial to assessing the effectiveness of laser detection for weak targets in complex coastal water bodies. We examine the theoretical and practical significance of understanding these factors in underwater laser detection. In this study, a laser detection model for detecting weak underwater targets is established. Monte Carlo simulation is used to verify the detection performance of weak multi-target laser ranging under different turbidities. The laser backscattering echo signals of weak targets at different distances are simulated, and the backscattering echo characteristics of multiple targets with various reflection coefficients are analyzed. Additionally, a smart and portable laser detection system for detecting weak underwater targets has been designed and developed. Laboratory and field lake environment tests were conducted to detect and range for multi-target. In a near-shore lake with a turbidity of 12.87 NTU, the system can effectively detect 3−4 mixed small target groups. These groups have different low reflection coefficients and diameters varying from 80 to 400 μm, all within a range of 10 meters. The average measurement error is ±0.11 m, which is consistent with the theoretical simulation results. The research results serve as a guide for computing links, designing systems, and optimizing parameters for detecting weak underwater multi-targets using blue and green lasers. Furthermore, the results assist in the engineering practice of detecting underwater obstacles in offshore turbid waters.
