Airborne-Combat-IDAirborne Combat ID brings with it a special set of constraints.  On-board systems have limited processing capability and have enormous demands put upon them.  In addition, communication links have limited bandwidth and therefore make ground processing untenable.  EMSI is developing Combat ID systems that fit well within these constraints.  By combining our reliance on compact image feature sets with a readily obtainable offline training data base, we enable integration of target identification into the battlespace.
