A -- BROAD AGENCY ANNOUNCEMENT (BAA 96-001) FOR THE NEED TO ACOUSTICALLY IMAGE OBJECTS IN HIGHLY TURBID WATER CONDITIONS SOL BAA 96-001 POC Renee DePalma, Contract Specialist, (301)743-6635. The Naval Explosive Ordnance Disposal Technology Division (NAVEODTECHDIV) has a need to acoustically image objects in highly turbid water conditions. The desired resolution is 1 cubic cm at a range of 3 meters. The current thrust is in technology areas related to acoustic lens based imagers and piezoelectric transducer sensors. Proposals for exploratory development are sought which address the piezoelectric transducer array, electronics and interconnects collectively known as the Acoustic Video Converter (AVC). A full sonar system proposal is not desired. The AVC transducers will be coupled to seawater in the image plane of a solid acoustic lens. The AVC should be capable of operating between 2.7 and 3.3 Mhz with transducer element sizes of 1 squared mm and center to center spacings of 1.75 mm. The electronic inputs will be power, timing and control data; the outputs will be timing and control data and an electronic data stream from the multiple sensors in the transducer array in a format suitable for image processing and display. The AVC will be used as a multibeam projector and receiver which will require some form of transmit/receive switching. Maximizing the sensitivity, dynamic range, and inter-element isolation of the AVC are key technical challenges. Power requirements, image updata rate, size and weight must be compatible with diver operations. This effort should consist of two phases. Phase one is a one year effort to design and deliver a proof of concept 10x10 element AVC which includes the electronics package for timing, and transmitting and receiving. The government will package the proof of concept AVC in an underwater housing for testing. Phase two, at the government's option, should be to design and deliver a 100x100 element AVC ready to be incorporated into an underwater imager. The five proposal copies should consist of three primary sections, Technical, Managerial, and Cost. The technical category shall consist of clear objectives, technical issues to be resolved to accomplish those objectives, approach to resolving those issues, and particular prio experience of offeror in the targeted technology area. The management section shall include key personnel (include curriculum vitae), experience, facilities and a plan of action with milestones. The Cost portion shall include a complete cost breakdown of the proposed effort (including direct labor rates, indirect rates, material costs, etc.). The cost of phase one should not exceed $320,000 and be completed in one year. The cost of phase two should not exceed $1,700,00 and should be completed in less than four years. The proposals shall be no longer than 50 single-sided pages. This program is an Office of Naval Research (ONR) funded effort. Evaluations of the proposals will be conducted using the following criteria: (1) Overall scientific and technical merit, (2) Proposal cost and fees, (3) The offeror's capabilities, related experience, facilities, techniques or unique combinations of these which are integral factors for achieving the proposal objectives, (4) The qualifications, capabilities and experience of the proposed key personnel who are critical in achieving the proposal objectives. Proposals are due by COB 30 Nov 1995. Proposals received at the closing date will remain on file for one year for consideration of award if funding is available. No award can be made without a proposal to perform specific effort within an estimated cost and time framwork. The Indian Head Division, Naval Surface Warfare Center (IHD, NSWC) anticipates that initaial selections will be made during the 2nd quarter FY96. (1) This announcement will remain open until 30 Nov 1995. Proposals will not be accepted after this date. Proposals may be reviewed and acted on as they arrive. The Government reserves the right to select for award all, some, or none of the proposals received in response to this announcement. It is the policy of IHD, NSWC to treat all proposals as competitive information and to disclose the contents only for the purpose of evaluation. Offerors shall submit proposals (original and four hard copies referencing BAA No. 96-001 to Indian Head Division, Naval Surface Warfare Center, Attn: Renee DePalma, Code 1143E, 101 Strauss Avenue, Indian Head, MD 20640-5035. All proposals submitted to IHDNSWC under this announcement solicits the participation of all offerors capable of satisfying the governments needs. The government will not cover any cost for proposal preparation, nor pay, as a direct expense peparation costs on awarded contracts. considered for award (0291)
