COUNTERMEASURE PROCESS IN THE FIELD OF TARGET EVALUATION AND LASER RANGE FINDING MATERIALS AND DEVICES FOR THE IMPLEMENTATION OF SAID COUNTERMEASURE PROCESS

摘要

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.
