Paper Abstract

Synthetic aperture radar (SAR) exploitation algorithms typically rely on the use of derived features to represent the target. These features are chosen to discriminate between target classes while exhibiting robustness to noise and calibration artifacts. One of the challenges in working with such features, is understanding when this assumption of robustness is no longer valid. In this paper, we focus on characterizing the performance of the gray scale quantization feature in the presence of additive noise. We derive an approximation for the variance of the intraclass distance by treating the additive noise as an independently identically distributed (iid) process. The analytic model is contrasted with empirical results for a two class problem.
