Abstract

The sensor is a hybrid IR/UV lidar system that maps aerosol clouds, measures cloud wind speed and direction, and determines whether the cloud fluoresces. It is being developed by EOO, Inc. and SRI International under a DARPA SBIR. The hybrid IR/UV lidar system was conceived to operate from a small UAV platform for tactical battlefield missions. The IR sensor can detect and map aerosol clouds out to ranges of several kilometers. After detection, the UAV can close to within several hundred meters of the cloud and interrogate it with the UV sensor to identify whether the UV cloud fluoresces. Both sensors use the same basic IR laser source that is non-linearly shifted to the appropriate UV wavelength. The IR sensor also provides wind speed using edge-filter Doppler information. Parametric studies during the Phase I SBIR provided performance vs. form/fit trade-off for various platforms. The tactical UAV was chosen as the platform to guide the Phase II brassboard development. Other airborne and ground-based platforms suitable for surveillance or intelligence can be used. The paper will describe the brassboard system and the sensor performance as validated by test data.
