Abstract

In this work, the radar processing technique of Range-Doppler processing is investigated for its potential to enhance performance of the radar-encoded laser system in rangefinding applications. One of the challenges experienced by this system is in discriminating between the returns from underwater objects and environmental clutter in highly-scattering and/or low signal-to-noise ratio conditions. The intention of this work is to investigate whether the addition of a new dimension, velocity, will improve ranging performance. This work presents the application of the Range-Doppler processing technique to transform data collected in a laboratory water tank. Results and performance improvements using the radar-encoded laser system are compared against those obtained with a conventional, short-pulse laser.
