A -- REQUEST FOR INFORMATION: EXISTING CORRELATION ALGORITHMS AND SYSTEMS POC Captain Lori McConnell, (719) 380-3830. The purpose of this announcement is to request information on existing correlation algorithms/systems for association of multiple data/information sources, particularly for intelligence sources. This Request for Information (RFI) is not a solicitation for proposals and is not intended to lead to the award of any contract. The Space and Missile Systems Center and Rome Laboratory, Griffiss AFB, NY, are supporting the Space Warfare Center in Project Correlation, an existing multi-phased project to categorize and classify existing correlation algorithms/systems for subsequent demonstrations and evaluations. In addition, information related to the potential for scaleability and correlation reusability of such algorithms/systems is desired. These algorithms/systems will be studied and the information provided will ideally be used to populate the Space Command Project Correlation Database. The database will be continually updated and maintained as the point source of information for USAF correlation algorithms and systems. FOCUS OF ANALYSIS: Phase I of Project Correlation entails categorization, classification, and study of existing intelligence correlation algorithms/systems. Subsequent phases may consist of future contractual efforts to evaluate correlation algorithms/systems that are representative of each classification category from Phase I and determine the potential for reusability. Thus, opportunities may arise for new applications of existing algorithms/systems whose descriptions are being requested. INFORMATION NEEDS: While independent efforts are being conducted within the Project to collect information on representative correlation algorithms/systems, this RFI is also being employed to collect detailed technical information on existing correlation algorithms/systems to improve the comprehensiveness with which the Project can categorize algorithms/systems, identify new requirements, identify extended applications of existing algorithms/systems, and determine unique approaches. The types of information being requested in this RFI, in addition to a block-diagram level overview and description of the algorithms/systems, are: (a) Description of domain of application, and nature and types of intelligence data able to be processed (e.g., single-INT, multi-INT, sensor/collector types, message types, etc.); (b) Whether measurement formation logic is included (e.g., redundant measurement elimination, clutter processing); (c) Whether observation alignment functions (bias removal or accommodation, time latency aspects, platform corrections, image preprocessing, etc.) are included within the overall processing capability; (d) Whether association/correlation is based on kinematic parameters, attributes, both, other, etc.--(i.e., basis for correlation); (e) Nature of processing (batch, sequential, etc.); (f) Nature of related gating procedures and techniques (e.g., multiple/special gates, coarse/fine gates, etc.); (g) Coordinate system within which correlation processes are conducted; (h) Nature of feasible hypotheses to which measurements can be assigned (in essence, the nature of the assignment problem framework and hypotheses permitted); (i) Method for assignment problem solution (e.g. Munkres, etc.); (j) Nearest neighbor or all-neighbors approach, or other; (k) Nature of association metrics (e.g., Bayesian-based or other); (l) Description of, and coupling/dependency to, host computing environment. Descriptive information is also being requested on any evaluations, tests, real-world application experience and/or any types of assessments of algorithm/system performance that may be available. All responses will be protected as proprietary information if marked as such. Personnel from the Aerospace Corporation, Geodynamics, and Calspan will be reviewing the responses along with Government personnel. A representative of the foregoing contractors will sign a nondisclosure agreement in order to protect any proprietary information within the responses. If any submitter has concerns about any of these contractors reading their response, the submitter should so state in their letter of transmittal, and the Government will work with the submitter to resolve the concerns. Responses may be classified up to and including Top Secret, Special Compartmented Information (SCI). Submitters are reminded that transmittal and marking of classified information must be in accordance with DoD 5220.22-M, ''National Industrial Security Program Operating Manual (NISPOM).'' Contact Capt. Lori McConnell at the phone number above to obtain procedural information on submitting a response. Please submit responses within sixty (60) calendar days after publication date of this announcement. (0159)
