A -- DEFENSE SYSTEMS RESEARCH & DEVELOPMENT SOL N00014-95-R-WJ04 POC Jamie Whitt, Contract Specialist, Code 3240.WJ, F. Janilea Bays, Contracting Officer (202) 767-1182. The Naval Research Laboratory (NRL) has a requirement for the development and field testing of an advanced shipboard electronic countermeasures (ECM) transmitter system. This requirement will be in support of an FY96 NRL Advanced Technology Demonstration (ATD) program entitled, ''Advanced ECM Transmitter for Ship Defense''. The contractor shall perform the initial development and demonstration of an ECM transmitter capable of successfully engaging modern threat weapon systems from the surveillance/targeting phases through the terminal run-in phase of an anti-ship missile. The contractor will be required to develop a fieldable brassboard ECM transmitter system which produces the required transmit beams over a full angular sector of 90 degrees azimuth by 50 degrees elevation. In accordance with the NRL notional design, the brassboard system must consist of a planar array of dual polarized flared notch elements, a power amplification network, a beamforming network, and a switching distribution and control network. The planar array must be an active aperture design and feature a modular, platform adaptable approach. The array must utilize true time delay for beam formation and steering. NRL's notional design requires four subapertures per quadrant, each of which must produce independent beams in any direction within the quadrant and at given frequencies. The subapertures must be capable of combining to produce higher radiated power when needed. The ECM transmitter system will be required to demonstrate the following: (1) multiple simultaneous beam transmissions throughout the full angular sector, (2) wide, instantaneous operating frequency bands within the H/I/J frequency bands, (3) polarization diversity, (4) remote active array interface, (5) advanced beamforming technology, (6) lower transmit beam sidelobes, (7) low quiescent transmitted noise, (8) reduced RCS contribution, (9) cost-effective transition to at-sea testing. The work will be divided into three phases. Phase I will consist of system and detailed design engineering. Phase II will consist of assembly, fabrication, integration, and land-based testing of the system at NRL's Chesapeake Bay Detachment testing facility. Phase III (Option 1) will consist of at-sea testing. Expertise in the analysis and design of advanced active antenna arrays, highly efficient monolithic microwave integrated circuits (MMIC) type amplifiers (including associated circuitry, advanced photonic beamforming/steering networks, and real-time calibration control networks) is required. Demonstrated hands-on experience and capability in the manufacture, fabrication, assembly, integration, and testing of high technology systems is required. A detailed Statement of Work will be issued with the solicitation. Period of performance is 36 months for the basic award (Phases I and II) and 24 months for Option 1 (Phase III). Telephone requests for this solicitation will not be honored.
