Description

The National Oceanic and Atmospheric Administration (NOAA), Environmental Technology Laboratory (ETL), (hereinafter referred to as government) is developing a Doppler wind light detecting and ranging (lidar) system for routine operation on the NOAA Gulfstream-IV (G-IV) aircraft. The lidar system will be side looking (through a cabin window) and will make line of site wind measurements on multiple horizontal planes looking fore and aft. The measurements will be used to provide clear air wind profiles spanning 10 km above and below the typical flight level of 40,000 feet. Major components of the lidar will include the laser transmitter, scanner, telescope and Doppler receiver. It is the government's intent to procure (1) a laser transmitter and (2) Doppler receiver components for the lidar system. The purpose of this request for information is to determine (i) if there are sources capable of satisfying the government's requirements; (ii) to determine availability of commercial items or, to the extent commercial items suitable to meet government's needs are not available, non-development items are available that ? (A) Meet government's requirements; (B) Could be modified to meet the government's requirements; or (C) Could meet the government's requirements if those requirements were modified to a reasonable extent; (iii) to determine the extent to which commercial items or non-development items could be incorporated at the component level; and (iv) to determine the practices of firms engaged in producing, distributing, and supporting commercial items, such as terms for warranties, buyer financing, maintenance, and packing and marking. No proposals are being requested or accepted under this synopsis. Feedback addressing the clarity, feasibility, scope, and potential alternative means of meeting the government's requirement is sought. The anticipated North American Industry Classification System Code (NAICS) for these requirement is 334511 and the small business size standard is 750 employees. NOAA will consider all comments, supportive or critical, but may or may not use these individual comments. In addition to comments, those interested are requested to provide a budgetary estimate for the System as specified herein. Interested Sources are also encouraged to submit product literature in response to this RFI. Any submission of such product literature or "catalog cut sheets" will be treated separate from, and will have no bearing on, any subsequent evaluation of proposals submitted in response to any resulting future formal Request for Proposals. NOAA will not pay for information or comments provided and will not recognize any costs associated with submission of comments. NOAA as noted above is assessing the existence of sources and is requesting written comments from industry on the requirements that follow. Written comments shall be submitted no later than 2:00 P.M. Mountain Daylight Savings Time, May 27, 2004. Sources interested in providing comments shall respond in writing to Mr. Daniel R. Gomez, Contracting Officer, DOC, NOAA, MASC, MC3, Acquisition Management Division, 325 Broadway, Boulder, CO 80305-3328. Submittals may be made via E-mail Daniel.R.Gomez@noaa.gov, Facsimile to (303)497-3163 or express delivery; however, telephone responses are not acceptable. This Notice is not a Request for Proposals, Invitation for Bid, or Request for Quotes. Laser Transmitter Requirements: The transmitter shall consist of a pulsed laser with an output wavelength of 355nm. Due to expected limitations in the receiver design, the pulse repetition frequency will be limited to less than 100 Hz. To maintain adequate sensitivity, the average power of the laser needs to be at least 10-12W and the laser needs to operate in single longitudinal mode with a frequency fidelity that is pulse transform limited. The laser transmitter shall have the following characteristics: Operating altitude: 42000 ft; Operating wavelength: 355 nm; Operating mode: pulsed; 20-30 ns pulse length; M2 < 2, TEM00; Average power: 10-12 W; Maximum pulse repetition frequency: 100 Hz; Single longitudinal mode; Single frequency; Bandwidth: pulse transform limited; Seeding lock servo loop bandwidth: up to 500 Hz; Flight qualified laser enclosure; Conductive cooling (must handle heatsink temperature excursions of +/- 2 deg C) and provide interface with an external cooling loop; Maximum 500W heat rejection into cooling loop; Approximate laser head specifications: Dimensions 26 X 15 X 5 (inches) (L X W X H); Weight < 66 lbs; Approximate laser power supply specifications: Dimensions 26 X 19 X 20 (inches) (L X W X H), Weight <145 lbs, Air cooled, 500W electrical power requirement; Serial communication control interface TTL trigger output; Computer control of laser functions. Doppler Receiver Requirements and other information: The receiver will analyze the backscattered radiation to produce estimates of the Doppler shift of the radiation relative to the transmitter wavelength and the backscattered signal power versus range. It is anticipated that light backscattered from molecules and aerosols in the atmosphere at 355 nm wavelength will be gathered by a telescope and focused into a multi-mode optical fiber, which will direct the light into the frequency analysis element. The Doppler receiver shall include this fiber. For consideration in the Doppler receiver design, the anticipated characteristics of the other lidar componentss are as follows: Operating wavelength: 355 nm; Maximum pulse repetition frequency: 100 Hz; Laser power: 10 watts; Output path transmission: 90%; Scanner and telescope: Holographic Optical Element (HOE); HOE free aperture diameter: 30 cm; HOE efficiency: 0.5 ; Field of view: 2 mrad. The Doppler receiver shall have the following characteristics: Operating altitude: 42,000 ft; Averaging time: Two seconds; Range Resolution: 1 km; Measurement precision: Better than 1 m s-1 to ranges of 15 km at 42000 ft altitude for a pure molecular scatter atmosphere; No loss in precision for aerosol/molecular scattering ratios above 1.0; Measurement bias: less than 1 m s-1; Range of Doppler shifts: The system shall be capable of measuring Doppler shifts equivalent to radial velocity component ranging from +350 m s-1 to -350 m s-1, in order to include the combined effects of wind speed and aircraft motion; Minimum range: 250 m; Ability to receive and process pulsed backscattered radiation at up to 100 Hz rate; Ability to average multiple pulses and produce estimates of Doppler velocity; User shall be able to specify and change averaging time, minimum averaging time = 1 s, maximum averaging time = 90 s. The receiver design shall include a capability to measure and compensate for pulse to pulse variability and drift of the laser pulse frequency when computing Doppler winds. This variability shall be recorded for analysis of laser characteristics. The receiver shall operate on the NOAA G-IV Aircraft. Size, weight, and power limitations are particularly important for aircraft operation. On the NOAA G-IV, the following specifications are anticipated: Ability to maintain stability with accelerations of +/- 3 g; Operating temperature range: 20-40C; Storage temperature range: -20 - 60C; Size: Receiver enclosure: No larger than 10 X 15 X 34 inches (L X W X H); Electronic rack : 26 X 19 X 43 (L X W X H); Weight: Receiver Enclosure: 70 lb; Electronics rack : 45 lb; Electrical power : <100 W; Cooling: A port has been reserved on the aircraft for installation of a radiator to dump excess heat to the atmosphere. The receiver cooling loop shall be capable of interfacing with, and providing cooling for the transmitter laser (500 watts) in addition to any cooling requirements of the receiver; Orientation and mounting: The receiver shall be capable of operating at any orientation Aircraft certification: The receiver shall be certified safe for aircraft operation. Interface and control: The receiver shall provide to the system control computer records comprising measured Doppler shift, calibrated backscattered power, and quality factor versus range. Records shall also include measurement time (UTC). The receiver shallould also archive any raw and intermediate level data necessary to enable post-flight troubleshooting and quality control. The receiver shall be designed to enable adjustment of major operating characteristics in real time through communication with the system control computer.
