The problem is to detect, classify, and remediate military munitions found in aquatic environments such as ponds, lakes, rivers, estuaries, and coastal and open ocean areas. A specific need is for technology to solve this problem with munitions residing in depths less than five meters. This shallow-water domain includes an assortment of unexploded ordnance that are the most likely to be encountered by the public and are expected to experience the most mobility. Many sensor technologies designed to detect, classify, and remediate munitions are challenged by this unique environment and suffer in performance, access, navigation, deployment, viewing, sensor standoff distance, and damage by changing bottom topography or obstructions. The project objective is to investigate how water conditions i.e. wavy surfaces and turbid water columns might impact the feasibility of using a new above-water lidar technology for the classification of the aquatic environment and the identification of munitions in waters less than five meters deep with vertical and horizontal resolutions at centimeter levels. The SEED-funded activity studied the interactions of pulsed laser light with wavy water surfaces and turbid water columns and their effect on the lidars 3-D mapping capability.
