Pulse coherent Doppler lidar signal processing on FPGA: implementation of the method of accumulation of a real autocorrelation function

The paper presents a new approach to implement the method of accumulating real autocorrelation functions on FPGAs to estimate the wind velocity from the signal of a pulsed coherent Doppler wind lidar. The proposed method provides lower resource consumption compared to the implementation of the method accumulation of power spectra.
