Abstract

A field trial has been conducted to obtain range performance data for two staring IR imagers and for a scanning first generation IR imager. Qualitative observer trials were made in the field. Perception experiments with the recorded imagery were made after the trial to obtain statistically relevant data. The field trial and the perception experiments are presented together with the observer results. Using the range performance of the scanning imager as a reference, the results obtained with the staring systems are compared with predictions made by range performance models. It is shown that a range model based on an MRTD which is limited to half the sampling frequency (Nyquist frequency) does not agree with the experimental results. Good predictions are obtained, however, with a range model based on the MTDP (minimum temperature difference perceived).
