ENSURING THE NATION'S SAFETY MITIGATING THREATS VIA AIR, LAND, & SEA   Advanced Sensor Systems   Hyperspectral and multispectral sensors enable stand-off detection of asymmetrical threats.   Unattended sensors support border, harbor and perimeter security.   Automated Identification Technologies facilitate biometric identification for tracking and entry/exit procedures.   Aircraft Security   Navigational and digital flight controls provide automatic diversion of aircraft from predetermined exclusion zones. Identification Friend or Foe (IFF) systems support identification of aircraft and mid-air collision avoidance systems.   On-board chemical, biological and video sensors monitor cockpit, cabin and baggage compartment security.   Radio Frequency (RF), Infra-Red (IR) jamming systems and decoy countermeasures (chaff, flare), provide aircraft self-protection.   Situational Awareness   Information Dominance Systems correlate and fuse multiple streams of data into a coherent tactical picture of relevant decision making information.   Information Technology   Image processing and exploitation systems support reconnaissance ground systems and sensor-to-shooter integration.
