Report from the Semark field trial at Kvarn Nov - Dec 2005

A Semark trial was performed on the Kvarn area in Nov-Dec 2005 (w. 47-48). A number of vehicles, mainly military, were then simultaneously registered with different sensors on the Prästtomta range. The vehicles were registered in different target scenarios, both during transportation on a road and stationary placed, on the road or in the terrain. During the trial the weather changed and therefore data were collected during two kinds of weather, cloudy and hazy with a temperature > 0 °C, and cold (<< 0 °C) and clear. Airborne registrations were performed with the two multispectral sensors Multimir and RedLake, which were mounted in the aeroplane Cessna 172. This report describes the data collected with these two sensors as well as the targets and the target scenarios in the trial. Multimir registers data in two spectral bands between 1.5-2.5 µm and in two bands between 3.5-5.2 µm. Redlake registers data in two bands between 530-690 nm and in one band in NIR between 770-830 nm. Thus the seven spectral bands of these two sensors cover the visual and the near infrared region as well as the short wave and middle wave infrared region. The collected data is a unique signature data base.
