Real Time LiDAR Signal Processing FPGA Modules

Aspects of the present disclosure involve a system and method for performing time of flight estimation of a laser pulse using a LiDAR signal processing. A plurality of digital waveforms are correlated to a transmitted pulse for time of flight estimation. Each of the plurality of digital waveforms can be correlated independently by a corresponding correlator in a plurality of correlators working in parallel. Each of the correlators can include signal processing modules for time of flight estimation including an interpolating filters and peak detect modules.
