Super-resolution technique for CW lidar using Fourier transform reordering and Richardson-Lucy deconvolution.An interpolation method is described for range measurements of high precision altimetry with repeating intensity modulated continuous wave (IM-CW) lidar waveforms using binary phase shift keying (BPSK), where the range profile is determined by means of a cross-correlation between the digital form of the transmitted signal and the digitized return signal collected by the lidar receiver.

This is then enhanced further using Richardson-Lucy deconvolution to greatly enhance the resolution of the pulse.

We show the sampling resolution and pulse width can be enhanced by about two orders of magnitude using the signal processing algorithms presented, thus breaking the fundamental resolution limit for BPSK modulation of a particular bandwidth and bit rate.
