Military Radar Systems
  Modern airborne radar in combination with improved navigation and communication capability has revolutionized warfare. The Modern Radar gallery shows the evolution from Korean War era radars to the present with hints of the future of radar.

The fire control radars AN/APG-63 for the F-15 and the AN/APG-68 for the F-16 aircraft indicate how improvements have been made in multimode capabilities, reliability (hundreds of hours between failures vs. a few hours between failures), less weight, and smaller size. Both make use of modern pulsed Doppler techniques that pinpoint enemy targets on the ground and in the air at long range - delivering information to the pilot and missiles for quick action.

Exhibits on AWACS and Joint Stars show how surveillance radars now dominate areas of conflict providing information of all activity in the air (AWACS) and on the ground (Joint Stars). Both systems have proven to be invaluable in recent conflicts in Iraq. AWACS is now used by six countries and NATO while the follow on Multi-role Electronically Scanned Array (MESA) Wedgetail system is deployed in Australia and will soon be deployed in other countries.

The exhibit on phased arrays shows the evolution of the modern and future radars with early examples of agile beam phased arrays which have led to the production version that are used on the F-22 and F-35 radars. Agile Beam Phased Arrays provide scanning, tracking and other functions controlled entirely by electronics with no moving parts, greatly enhancing system performance and response time.

In This Exhibit:
  • A TPS-43 and TPS-70 ground based tactical surveillance radars in an outside exhibit area.
  • An AWACS antenna including a mock-up of the radome
  • Radar tracks of incoming flights at BWI Thurgood Marshall Airport
  • A hands on demonstration of phased array beam steering
