J -- MAINTENANCE AND/OR REPAIR OF EQUIPMENT - POTENTIAL SOURCES SOUGHT A source seeking synopsis is being conducted to find sources interested in the maintenance of an AP/APD-14 Radar Imaging Set. This is not a solicitation to do business. This is a market survey seeking interested sources. The requirement is for depot level maintenance, to include hardware and software on the radar imaging set commonly referred to as the Synthetic Aperture Radar (SAR). The ADP-14 consists of a right and left antenna, analog front end and a digital back end. All maintenance will be completed at the contractor's facilities with contractor repair procedures. No unauthorized modifications or improvements to the systems will be allowed. The contractor will be required to serve as crew members, if necessary, in order to troubleshoot the SAR. The AP/APD-14 is a custom-built SAR, With a limited application. The SAR will only be installed in two OC-135B aircraft, with one complete SAR system as spares for the two active systems. The SAR was developed from UPD-8 (retired) and a custom-built processor to convert the analog signal into digital, then store it on magnetic tape. The UPD-8 was refurbished removing the old `sunset technologies' and replacing it with up to date components. All excess UPD-8 LRUs and test equipment in the Air Force inventory are being stored in case more modified spares are required. If this becomes an issue, the contractor will be required to do the modification. There is only one digital spare processor. It is a custom-built computer, designed specifically to convert the analog signal and provide for Open Skies Treaty required annotation on magnetic tape. This requires the contractor to have extensive knowledge on troubleshooting computer software code and hardware applicable to the synthetic aperture radar. Sources should express their interest in writing to OCALC/CR; Attn: Ken Thomason; 8745 Entrance Road A; Tinker AFB, OK 73145; FAX 405-739-2699. (036)
