Abstract
The countermeasure process in the field of target evaluation and laser range finding consists in coating at least a portion of a missile with a doped material that absorbs at least a portion of the incident laser beam and reemits a diffuse radiation in a different waveband. The reemission wave length preferably corresponds to an absorption spectrum band of the atmosphere. A portion of the reemitted signal can be used to trigger an alarm. This invention also covers the materials for the implementation of the countermeasure process, they are made of a matrix that is doped with photoluminescent substances. Applications: varnish, paints, canopies, helmet vizors.
