Light detection and ranging (LIDAR) is currently used for bathymetric measurement or underwater target detection. A
new underwater-target detection scheme named modulated lidar was recently proposed. The study reported here deals
with optimization of the modulation process to be applied under such detection conditions. A theoretical model was
extracted from available experimental results by deconvolution and further used to simulate realistic backscattered
signals for the development of a new modulation scheme. Then, an optimum set of amplitude modulation code
parameters was obtained by maximizing the target signal-to-noise ratio. This paper will highlight some particularly
promising waveform configurations.
