Abstract

To retrieve a high-resolution vector signal from a set of measured low-resolution vector signals, we deliberately delayed the synchronization between the transmitter and the receiver of a pulsed laser radar (lidar). Once several range-shifted low-resolution vector signals had been obtained, we independently applied a regularization method and the singular-value-decomposition method to restore high-resolution characteristics. The former approach remains preferable when the signal-to-noise ratio is low, whereas the latter provides results similar to those of the former, but with lesser effort, as the signal-to-noise ratio becomes high.
