Fourier Coefficients Applied to Improve Backscattered Signals in A Short-Range LIDAR System

Abstract: Light Detection and Ranging (LIDAR) is a remote sensing technique that measures properties of backscattered light in order to obtain information of a distant target. This work presents a method to improve the signal-to-noise ratio by 8 dB with respect to the direct detection of the backscattered signal of a LIDAR system. This method consists of the measurement of the Fourier coefficients of the LIDAR signal, which is possible thanks to the novel coupling of a sequential equivalent time base sampling (SETS) cir… Show more

“…Lastly, the noise power spectral density, originating from various sources, introduces background noise that affects the overall signal-to-noise ratio. Careful consideration of these factors is crucial for maintaining reliable communication in drone networks [5], [6], [7]. In [8], they delve into the realm of drone-assisted backscatter communication within an Internet of Things (IoT) sensor network.…”
