U.S.Army Space and Missile Defense Command, ATTN: SMDC-CM-CN, PO Box 1500, Huntsville, AL 35807-3801/106 Wynn Drive, Huntsville, AL 35805-1990

A -- NATIONAL MISSILE DEFENSE (NMD) GROUND BASED RADAR (GBR) TESTBED POC Dianne Trimble, Contract Specialist/Linda N. Bentley, Contracting Officer, SMDC-CM-CN, (256)955-1187 The U.S. Army Space and Missile Defense Command (USASMDC) intends to enter into a noncompetitive contract for National Missile Defense (NMD) Ground Based Radar (GBR) Testbed. The objective of this effort is for continuation of support to the NMD-GBR Project Office (PO) in the areas of Hardware in the Loop Independent Verification and Validation (HWIL/IV&V) and Radar Testbed activities including (1) simulation architecture design and development; (2) unique radar signature generation simulation for interfacing with NMD-GBR tactical hardware and software; (3) development of prototype software to assess objective radar system requirements; (4) providing capabilities to connect with GBR-PO hardware at the U.S. Army Kwajalein Atoll (USAKA) for Sim-over-live activities; (5) providing total software verification support including documentation review and requirements traceability; (6) software validation to include software testing, software problem reporting, configuration management, and algorithm analysis; and (7) mission support of USAKA flight tests which includes software performance analysis, data repository, and pre-mission predictions. The GBR HWIL Testbed is being developed to reduce the risk involved in having a limited number of flight tests and targets for the NMD Integrated System. The GBR HWIL Testbed integrates the GBR Prototype (GBR-P) tactical hardware and software with a Target Complex Generator (TCG) that is capable of generating target returns (1) in real-time, (2) with high fidelity, and (3) in large numbers in a variety of environments. The GBR HWIL Testbed will be used to provide a high fidelity NMD-GBR analysis tool capable of supporting a multitude of tasks. These include supporting software IV&V and the analysis of software to meet mission requirements; determining the performance boundaries and limitations of the current hardware/software configuration against all threats and in NMD environments and conditions; and evaluating algorithms associated with discrimination, kill assessment, and In-Flight Target Updates (IFTU) and Target Object Map (TOM). The GBR HWIL Testbed will also be utilized for predicting the GBR-P software performance for flight tests and Targets of Opportunity (TOOs) at USAKA, as well as analyzing software algorithm anomalies. By adding a simulation-over-live capability at USAKA, the GBR HWIL Testbed will be able to perform antenna electrical/ mechanical scan analysis while performing in a variety of different environmental effects. The GBR HWIL Testbed will also provide a robust architecture that will accommodate insertion of new antenna phased array technologies, such as Advanced Digital Beamforming, and advanced signal processing capabilities. Under the authority of Federal Acquisition Regulation (FAR) 6.302-1(a) (2)(iii), this action is directed toward Colsa Corporation. This notice of intent is not a request for competitive proposals; however, responses received from interested sources will be considered by the government. This acquisition is not open to Allied participation. All responses should be directed to SMDC-CM-CN/Dianne Trimble and must be received within fifteen (15) days from the publication date of this notice. A determination by the government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the government. Posted 07/23/98 (I-SN227653). (0204)
