Abstract

In this work, we investigate the use of a radar processing technique to enhance detection performance of a short pulse laser system. One of the challenges experienced by this system is discriminating between the return from an underwater object and the clutter return caused by backscatter in highly-scattering and/or low signal-to-noise ratio (SNR) conditions. Taking inspiration from the radar processing community, we apply the Range-Doppler processing transform to data we collect in our laboratory water tank. This work will present the modified Range-Doppler technique, provide laboratory test tank results, and demonstrate performance improvements achieved using the modified Range-Doppler technique.
