1.Along with the development of ECM and target stealth technology, besides countering ground, sea and weather clutter, it requires the radar having capability of extracting useful small target under all kinds of contrived electronics jamming so as to keep good matching status between radar and battlefield. Thus, the radar should adopt a "high sensitivity, multi-function and adaptive" signal processing system.
3.In this paper section 2 introduces the design of the original APG-76, section 3 is the added feature of the improved radar and renamed it as APG-76 (V), itsadded feature is detection the smuggling moving ground (or sea ) targets by using SAR technique. Section 4 gives out the performance evaluation about the APG-76 (V) in the year 1997 after flyingtests.
6.I have directed the Secretary of Defense to proceed with fielding an initial set of missile defense capabilities. We plan to begin operating these initial capabilities in 2004 and 2005, and they will include ground-based interceptors, sea-based interceptors,additional Patriot (PAC-3) units, and sensors based on land, at sea, and in space.
