Abstract
The advantages and limitations of using the pseudorandom-noise (PN)-co de technique in comparison with pulsed direct detection are discussed. Because the signal-to-noise ratio (SNR) of the PN codes is dependent on the average atmospheric return, strong returns from short ranges an d clouds determine the SNR for all ranges. The SNR of a profile obtain ed by pulsed direct detection exceeds that of the PN-code technique fo r laser beams with the same average power. (C) 1997 Optical Society of America.
