Simulation analysis of modulated lidar on optical carrier for target detection in deep-ocean

摘要

In the deep-ocean target detection, under water contrast is limited by incoherent backscatter clutter, and unable to meet the requirements. Modulated lidar on optical carrier technology which detects the target in deep-ocean can effectively inhibit the seawater backscatter and improve target's contrast. The system of modulated lidar on optical carrier for target detection in deep-ocean is simulated by computer, and the results show that detection effects are significant improved, and seawater parameters and modulation parameters have significant impact on the detection performance.
