CW Lidar signal processing System IP
CW Lidar signal processing IP consists of N-step digital filters.
The described IP has the advantage of using a low number of sampling rate digital data and a low number of FFT points.
By applying the CFAR algorithm to a digital signal that passed through the N-step digital filter, more accurate distance measur..
Zoom FFT CW Lidar system IP
FMCW Lidar system IP with variable point FFT and analog filter.
The Beat Frequency is extracted from the transmit and receive waveforms and passed through an analog filter of N-step to perform Fourier Transform in the low band.
Send the filtered analog signal to the FPGA to estimate the original Beat Frequency to o..
