Abstract In the future intelligent war, new challenges for detection, perception, command and decision of air defense and anti-missile weapon systems are required and have been put forward. Focusing on intelligent perception countermeasure to empower future air defense and anti-missile combat equipment, the concept and connotation of intelligent perception were analyzed. Centered on the OODA(Observe, Orient, Decide and Act) ring and the typical combat process, the main forms of sensing countermeasures were elaborated, including warning and counter warning, detection and counter detection, and tracking and counter tracking. The core scientific problem was identified, which was feature concealment and recognition. The main application scenarios of perception countermeasure technology in the OODA ring were revealed. Finally, the key technologies that need to be developed to enhance the intelligent level of perception concealment for air defense and anti-missile weapon systems have been proposed.
