Abstract:With the rapid development of infrared imaging detection and guidance technology, the suppression ability of traditional passive artificial decoy jamming release methods on optoelectronic detection and guidance systems has significantly decreased. In the air-to-air offense and defense game, this seriously threatens the survivability of the carrier aircraft. To ensure an advantage in optoelectronic countermeasures, laser-directed infrared countermeasure (DIRCM) technology has received extensive attention. By means of active directed energy irradiation and interference, this technology can effectively suppress optoelectronic detection systems and render them ineffective. In recent years, laser DIRCM systems have gradually matured and achieved good results in relevant verification tests. This paper reviews the development status of airborne laser DIRCM technology. Through the analysis of its working mechanism and technical characteristics, countermeasure technology suggestions are put forward from the perspective of optoelectronic detection and guidance systems, with a view to maintaining an advantageous position in optoelectronic countermeasures.
