IRST/EODAS作为重要的被动传感器,可以在雷达保持静默时实现态势感知,并引导AAM进行攻击,避免火控雷达开机导致被敌方发现,F35的EODAS还有导弹告警功能。F-22列装时EODAS尚未成熟,并不是对空优机不重要。以下是诺格官网上对F35的AN/AAQ-37的说明: Northrop Grumman has developed the only 360 degree, spherical situational awareness system in the electro-optical distributed aperture system (DAS). The DAS surrounds the aircraft with a protective sphere of situational awareness. It warns the pilot of incoming aircraft and missile threats as well as providing day/night vision, fire control capability and precision tracking of wingmen/friendly aircraft for tactical maneuvering.
Designated the AN/AAQ-37 and comprising six electro-optical sensors, the full EO DAS will enhance the F-35's survivability and operational effectiveness by warning the pilot of incoming aircraft and missile threats, providing day/night vision and supporting the navigation function of the F-35 Lightning II's forward-looking infrared sensor.
