Abstract

Laser radar systems historically offer rich data sets for automatic target recognition (ATR). ATR algorithm development for laser radar has focused on achieving real-time performance with current hardware. Our work addresses the issue of understanding how much information can be obtain from the data, independent of any particular algorithm. We present Cramer-Rao lower bounds on target pose estimation based on a statistical model for laser radar data. Specifically, we employ a model based on the underlying physics of a coherent-detection laser radar. Most ATR algorithms for laser radar data are designed to be invariant with respect to position and orientation. Our information-theoretic perspective illustrates that even algorithms that do not explicitly involve the estimation of such nuisance parameters are still affected by them.
