Target signatures for laser altimeters: an analysis

Research output: Contribution to journalArticlepeer-review


The statistical characteristics of the received signal for short pulse laser altimeters are investigated. Expressionsare derived for the mean and temporal covariances of the received pulse for a direct detection receiver.The effects of laser speckle, shot noise, and surface profile of the ground target are considered. Theresults are used to compute the means and variances of the total received energy, propagation delay, and rmswidth of the received pulse. These parameters are shown to be directly related to the statistics of the surfaceprofile.
