Airborne multi-sensor platform with potential for hydrological applications: demonstration of fluorescence measurements of turbidity

摘要

The multi-sensor system installed on a Do228 aircraft is used in Germany for operational surveillance for maritime oil pollution. It includes radar, a laser fluorescence sensor and other near-range sensors with ultra-violet, thermal infrared and microwave channels. This system is dedicated and specialized for the detection and characterization of maritime oil spills. Nevertheless, it has potential for hydrological applications, e.g. the monitoring of turbidity or suspended particulate matter (SPM). Laser fluorescence measurements along the tidal River Elbe correspond well to the expected characteristics of turbidity distribution. Even the correlation with point measurements of SPM concentration shows promising results.
