Abstract: Target detection theory is developed for 3-D pulsed imager operation of a coherent laser radar in a downlooking scenario. Generalized likelihood-ratio tests (GLRTs) and receiver operating characteristics (ROCs) are presented for range-only and joint-range-intensity processors. This work extends previous studies in three ways: (1) fine-range information is included; (2) maximum-likelihood estimation of an unknown range plane is performed; and (3) connections to Markov random field preprocessing are established.!
