Advanced Digital Signal Processing for Hybrid Lidar
Abstract
A spatial filtering approach to reduce the effect of backscattering continued to be investigated. Work to date based on RangeFinder simulations and post-processing of Navy experimental data has shown that the use of delay line cancelers in single and dual-tone modulated hybrid lidar-radar leads to an increase in usable range of approximately 35%. Additionally, reductions in range error on the order of 10%-20% were observed for a single-tone system, and reductions on the order of 60% observed for a dual-tone system. Mr. Paul Perez reported some of this work at the Oceans 2012 conference in October (reference provided below). A more comprehensive summary report of the spatial filtering approach is presented here. With ONR approval, Mr. Paul Perez completed his effort on the ULI project and Mr. David Illig, a Ph.D. candidate at Clarkson University, replaced him. Mr. Perez successfully completed his Master of Engineering Degree. Mr. Illig will continue to advance the spatial filter work and will investigate several new signal processing techniques that have been identified including a frequency domain approach to reducing backscatter.
