Paper Abstract

Passive Millimeter Wave Systems often have low spatial resolution which limits the size of detectable objects. However, there are some special cases in which objects that do not completely fill a pixel may be readily detected. The geometry of wires and pipes make them particularly visible, although the contrast can vary rapidly with detector - target geometry. In this paper a model is developed for the contrast of a reflective cylinder against an arbitrary background. Experimental data is presented from a high clutter environment that shows sub pixel detection in practical environments.
