| 1 NAME OF PROPOSED SOLE SOURCE CONTRACTOR BRAND NAME MANUFACTURER: REMTECH INC THOMAS SCHREIBER 2008 PEACEFUL PLACE THE VILLAGES FL 32162-3860 TELEPHONE NO: 303-772-6825 NAICS 334519 |
| 2 BRIEF DESCRIPTION OF SUPPLIES OR SERVICES REQUIRED AND THE INTENDED USE: The Aberdeen Test Center's (ATC), Atmospheric Effects Team (AET) requires a new REMTECH PA0 Sodar System to provide its test mission with medium range, consistent-accurate, near real-time, upper level wind data for managing daily operations. This particular system has customized data acquisition and processing algorithms. In addition, it has solar capability, lightweight and has a small footprint required for installation by the AET. Currently, The AET's permanent SODAR systems are no longer operational or supported by their manufacturer due to the company being sold. This system "is urgently" required to support daily firing test, noise modeling, four-dimensional weather forecasting and overall to provide public safety alerts before and during testing operations. |
| 3 UNIQUE SALIENT CHARACTERISTICS THAT LIMIT AVAILABILITY TO ONLY ONE SOURCE WITH THE REASON NO OTHER SUPPLIES OR SERVICES CAN BE USED: The PA0 acoustic wind profiler measures a vertical profile of wind speed, direction, thermal stratification and turbulence parameters (sigma W, sigma Theta) up to 700 meters. The system is small and weighs less than 60 pounds. The PA0 has only one antenna, and the steering of the beam is performed by phase control among the antenna elements. Consequently, no large antenna enclosure is needed due to tapering of the amplitude. Background noises during measurements (i.e. Testing, personnel working and overall outside noise) can interfere with the SODAR measurement causing the returning signal to be no good. Consequently, the wind field is not measured! Through software, REMTECH is able to provide a signature to the transmitted pulse. The basic coding consists of transmitting up to 30 frequencies in the pulse. Upon reception, this coded pulse is easily detected from noise and fixed echoes within the backscattered signal. This is particularly useful for turbulence studies since it allows quicker detection for full analysis on the noise spectrum. The technique has been used for years in radar, REMTECH is still the only company to apply this to SODAR (US Patent No 5,521,883).The frequency transfer function (in phase and amplitude) between the "active antenna" and the "reference antenna" (made of 4 transducers at the 4 antenna corners) allows a very efficient noise subtraction, especially for a fixed noise source such as an air conditioner or an aspirated shield on a meteorological tower close to the sodar. The final acoustic frequency power spectrum can be cleaned by more than 15dB's decrease of the jamming source in the considered frequency zone. This noise subtraction technique is also very efficient to removing spurious frequency peaks which can be generated by electrical and/or magnetic influence. There is no other equipment available that can provide all of the above required characteristics. |
| 4 REASON WHY CONTRACTOR IS THE ONLY SOURCE CAPABLE OF MEETING MISSION REQUIREMENTS SPECIFICALLY THE REASON NO OTHER SOURCE CAN MEET THE UNIQUE CAPABILITIES IN SECTION 3 Is this a followon contract yes no If yes provide contract number: How would award to any other source result in substantial duplication of cost to the Government that is not expected to be recovered through competition? Currently, The AET has a portable REMTECH Sodar (PA-XS) that was procured in 2017. The team was trained in all aspects of software and operation by the vendor. The new software and operation is identical for the PA0 model. Therefore, training and operation costs will be saved. Meteorologist are trained and familiar with all specialized algorithms and display interpretation for vectorial presentation of vertical profile of horizontal wind, facsimile presentation of all data, multi-level times series presentation of all data, sigma w computation, sigma theta computation, automatic temperature inversion detection and automatic mixing height/depth calculation. |

| 5 MARKET RESEARCH: What market research has been conducted and how recently? Describe procurement history. What market research is your agency conducting to identify alternative sources/products/service providers for similar actions in the future? |
Market research was conducted back in early Feb/Mar of 2019 by utilizing search engines on the Internet. GSA Advantage was also researched for this effort with no success. In the future, ATC will continue to research periodicals and journals to identify new technology sources. Currently, other methodologies LIDAR/RADAR are 5 to 7X more expensive than SODAR technology. UAV weather sensing development is not matured at the time of this procurement but may be a more cost effective means in the future. REMTECH model PA-XS was recently procured by AET in

| Reason why contractor is the only source: REMTECH is the only vendor that has SODAR, remote powered and codes the signal transmitted so that the returning data can be discriminated accurate from any noise. In addition, REMTECH is only vendor that has a patent for noise subtraction for fixed sources. They have no authorized resellers. No other source can fill the requirement. The mission will lack accurate upper air wind data profiles. Data are required to support testing for all caliber firing programs (firing tables), aiming tables, production, mortar tests ("Go/No Go decisions) as it improves data trajectory processing to build more accurate ballistic models. No additional training will be needed. Continuity of testing will only be affected in so much that accurate wind profiles are not obtainable to support modeling and ballistic related tables.? The government will not obtain any additional costs. This requirement is not flexible due to no other vendors found whom can provide this supply. | |
