The Use of Artificial Cloth Targets for
Positioning Airborne Scanner Imagery

The detection of specific features to be used in
attitude control of airborne scanned electro-
optical imagery is often impeded by viewing
geometries and terrain variations. To reduce
dependence on natural features, artificial targets
are deployed which will give good visibility on
frame photography, and in the digital data which
is collected in various wavelength windows. The
spectral response of the cloth material, the
surrounding surficial features and environmental
effects are contributors to the variances by which
target detection can be performed. The paper
reports some experimental results in the
definition of the target's geometry, its field
deployment and its detection in both air photo and
digital, multispectral scanner imagery.
