Infrared imagery from various terrain backgrounds have been collected by the Environmental Research Institute of Michigan and analyzed to determine the statistics of both radiometric and spatial features. This paper describes some of the characteristics in the form of histograms, equivalent ellipse statistics, and power spectra for several infrared bands. Data are included for nine wavelength regions of common interest. These were acquired over a variety of terrains during the four seasons and at various times of the day and night. Additionally, the industrial target data collected as part of the development of a DARPA image data base for autonomous terminal homing technology evaluation is described. The terrain backgrounds data were collected with the ERIM M-7 scanner, a multispectral scanner which operates in several wavelength bands in the visible and infrared portions of the electromagnetic spectrum. The terrain backgrounds imagery were collected with the scanner looking both downward and in a direction 35° below the horizontal. The industrial target imagery was collected using an ERIM-modified Reconofax X scanner. The target imagery was collected at depression angles of 6, 10, 20, 75, and 90 degrees.
