A. (U) MISSION DESCRIPTION AND BUDGET ITEM JUSTIFICATION: The Naval Space Surveillance Fence is an integral component of the U. S. Space Command Space Surveillance Network. This system provides continuous surveillance and unalerted detection of space objects crossing the Continental United States (CONUS). The fence is also the only space surveillance system which provides satellite vulnerability and space control data to the fleet units. It is a multistatic continuous wave radar fence consisting of three transmitter sites, six receiver sites, and a computation/communication center. The transmitter and receiver sites are located on a great circle across the southern CONUS, and the computation/communication center is located at Naval Space Command.

(U) JUSTIFICATION FOR BUDGET ACTIVITY: This program is funded under OPERATIONAL SYSTEMS DEVELOPMENT because it encompasses engineering and manufacturing development for upgrade of existing operational systems.

(U) PROGRAM ACCOMPLISHMENTS AND PLANS:

1. (U) FY 1996 ACCOMPLISHMENTS:

(U) ($250) Prototype and testing completed on fence improvements in accuracy, sensitivity and modeling.

(U) ($150) Completed initial study on integration of optical and fence detection.

(U) ($232) Demonstrated improved calibration techniques for fence operations.

(U) ($80) Developed improved atmospheric drag prediction.

2. (U) FY 1997 PLAN:

(U) ($121) Complete development of integrated and optical fence sensors.

(U) ($182) Prototype high risk components of next generation fence.

(U) ($150) Initiate development of prototype transmitter module.

(U) ($206) Improve accuracy and consistency of angular resolution and chirp processing techniques.

(U) ($18) Portion of extramural program reserved for Small Business Innovation Research Assessment in accordance with 15 USC 638.

3. (U) FY 1998 PLAN:

(U) ($200) Develop and evaluate prototype X-band feed assembly as part of antenna array.

(U) ($100) Evaluate site distribution impacts to current system of X-band implementation.

(U) ($99) Demonstrate impact of high volume processing (10-100 times) on multiple site integration.

4. (U) FY 1999 PLAN:

(U) ($529) Initiate integrated prototyping and evaluation of next generation fence capability. Demonstrate and prototype remote processing of observation data. Evaluate transmitter module improvements.

B. (U) PROGRAM CHANGE SUMMARY:

	FY 1996	FY 1997	FY 1998	FY 1999
(U) FY 1997 President's Budget:	729	706	707	860
(U) Adjustments from FY 1997 PRESBUDG:	-17	-29	-308	-331
(U) FY 1998/1999 PRESBUDG Submission:	712	677	399	529

(U) CHANGE SUMMARY EXPLANATION:

(U) Funding: FY 1996 adjustment is due to administrative and personal services rescission (-5) and SBIR assessment (-12). FY 1997 adjustment is due to Congressional Undistributed Reductions (-29). FY 1998 adjustment is due to internal navy adjustments (-307) and inflation (-1). FY 1999 adjustment is due to NWCF and other minor adjustments (-329) and inflation (-2).

(U) Schedule: Not applicable.

(U) Technical: The funding decrease in FY 1998 eliminates efforts to integrate sensors on a near real-time basis, reducing the ability to analyze orbital anomalies and reduce drag modelling, currently the biggest variable in low orbit and re-entry predictions. FY 1999 funding reductions reduce efforts towards fence replacement acquisition increasing the technical and cost risk for the required FY 2003 implementation.
