Paper Abstract

Maximum-likelihood range profiling is considered for pulse-dimager operation of a coherent laser radar. In particular, the expectation-maximization algorithm is used to develop a computationally simple procedure for fitting a planar surface to laser radar range data. Basic analytic properties of the algorithm are reviewed and results based on simulated and real range data are presented.
