Research progress of lasers in directional infrared countermeasures system
The rapid development of infrared precision-guided technology has led to a rapid decline in the counter-measure effectiveness of traditional infrared decoys,infrared omnidirectional jamming and other protective meas-ures.The directional infrared countermeasures system only radiates laser during interference,with narrow beam,con-centrated energy,no need for heating,and strong concealment and timeliness,which is the mainstream platform for dealing with infrared precision guided strikescurrently.As a core component of directional infrared countermeasures system,laser source plays a significant role in jamming efficiency and has been receiving much attention.The research progress of six types of laser sources,such as quantum cascade lasers,which can be used in directional infrared coun-termeasure systems,is introduced,and an outlook on the future trend of directional infrared countermeasure systems is given in the light of the integration,stability and adaptability of laser sources.
