Paper Abstract

An experiment is conducted to observe painted aluminum panels across long-wave, mid-wave, and short-wave regions of the optical infrared spectrum with respect to time. Simultaneously, comprehensive meteorological information including solar intensity, temperature, humidity, and moisture are also recorded. The experiment is focused on 1) understanding the cause of signature variability of several objects in the scene in relation to numerous meteorological conditions, 2) observing the potential benefit offered in passive polarimetric sensing, and 3) identifying the strengths and limitations of each waveband for the encountered condition. Metrics include intensity, polarization, and contrast from multiple wavebands measured across various solar conditions against painted panels and natural clutter. We present details of the experiment setup, analysis of imagery and meteorological data, and observations drawn from experimental results.
