B. (U) BRIEF DESCRIPTION OF MISSION REQUIREMENT AND SYSTEM CAPABILITIES:
(U) This project addresses advanced radar system designs and critical component technologies needed to
build long range radar systems with search, detection, tracking, discrimination and kill assessment
functions for multiple targets. Targets are threat ballistic missile reentry vehicles and associated
objects at both endo- and exo-atmospheric ranges. This project provides the critical technologies for
current as well as future radar systems that support BMDO architectures.
(U) As a result of the Secretary of Defense's Bottom-Up Review (BUR) in FY94, funding for the Radar Technology activities was reduced to approximately 16% of the FY93 level, and 25% of the planned FY94 expenditure. FY94 represents a transition year in which efforts will change focus from elements that support theater GBR to develop innovative concepts for a wide variety of theater radars.
(U) Large Radar Technology: This program is developing an advanced radar technology base necessary to
meet the functional performance requirements of large aperture, phased array radars to support ballistic
missile defense during all phases of threat flight. Emphasis is placed upon endo- and exo-atmospheric
tracking, fire control, and engagement functions with focus on developing solid state RF components,
fiber optic interconnects and waveform generating and processing components.
(U) Innovative Radar Technology: This program is developing radar technologies which have direct
benefit for national and theater radars operating in electronic countermeasure and nuclear environments.
Projects planned include techniques to coherently combine signals radiated from multiple radars, resonant
target identification phenomenology, synthetic aperture radar hardware and demonstrations, and track
error compensation technologies.
(U) This project is assigned to the Budget Activity and Program Element codes as identified in this
descriptive summary in accordance with existing Department of Defense policy. Further justification of
the Budget Activity code assigned to each Program Element is contained within the Brief Description of
Element section of each Program Element Summary.

E. (U) COMPARISON WITH FY 1994 DESCRIPTIVE SUMMARY:
1. TECHNICAL CHANGES:
o Currrent funding maintains core radar technology work while program is redirected.
o Establishment of RFSS/ARC Optical Communications link stopped.
o Drop Synthetic Aperture Radar Demo Plans
2. SCHEDULE CHANGES:
o Delay FY94 Advanced Radar Component Technology Program Award (9mo's)
o Delay Advanced Active Aperture Contract Award (FY94 to FY95)
o System Demo schedules for Enhanced GBR Operation slipped by 1 year
3. COST CHANGES:
o Reduction in FY94 funding of $4.913M from April 93 mark of $6.544M to the present mark of $1.631M.
F. (U) PROGRAM DOCUMENTATION: Solid state module and Waveform Generator/Return Simulator Hardware
Demonstrations and associated test results.
G. (U) RELATED ACTIVITIES:
(U) Supports the effort to build and test the demonstration/ validation Ground Based Radars in 1995-96,
and the independent radar discrimination engineering developments needed for exo-atmospheric target
identification. These technologies further complement radar enhancement programs being undertaken in the
BMDO Theater Missile Defense office (TMD). There is no unnecessary duplication of effort within BMDO or
the DoD.
