A -- RESEARCH AND DEVELOPMENT SOURCES SOUGHT, ULTRA-WIDE BAND ANTENNA SYSTEM Due 041996. Contact Steve McCarthy, Contract Manager, (513) 254-7950. Ogden Professional Services Corporation, Lawrence Associates (OLA), a Prime Contractor to the Department of the Air Force under contract F33615-94-D-1406 requests expressions of interest to support initiation of a potential program to develop an Ultra-Wide Band (UAB) antenna. The letters of interest are due by 1500, 19 April 1996. This foliage penetration (FOPEN) radar antenna is intended for use on Unmanned Aerial Vehicles (UAV) type platforms. The operation of a radar sensor capable of finding targets hidden under foliage, and capable of operating from an UAV such as the Tier II+, requires the development of a specialized Very High Frequency - Ultra High Frequency (VHF-UHF) Ultra Wide Band (UWB) antenna. Previous efforts in this area have used Quad-ridged horns which are very bulky and require large amounts of power. Antennas such as these are inappropriate for UAV applications, where strict volume, weight and power consumption requirements must be met. This antenna development will focus on such issues as power, size, weight, cooling use of multiple polarizations and the methods for platform integration. This antenna development should be vectored toward the Tier II+ (Global Hawk) UAV with a nominal operating frequency range of 25-500MHz. Because of the desire to integrate the resulting antenna onto a Tier II+ UAV, it will be necessary for potential participants to demonstrate that they have both the competence and the ability to work with the developer(s) of the Tier II+ platform to ensure that the antenna design accounts for the unique features of the Tier II+ platform, and that the necessary integration can be achieved with minimal impact on the Tier II+ design. This announcement is to ensure that all potential offerors have an opportunity to participate in this program. There will be no further announcements made regarding this activity. This announcement does not guarantee that a request for proposal will be issued to procure this effort. All interested offerors should submit a letter of interest to: Mail; OLA, 5100 Springfield Pike, Suite 509, Dayton, OH 45431; or, FAX 513-253-2296. The letter of interest should provide the full name and address of the offeror, telephone, FAX, and e-mail addresses for the individual(s) who are the designated point(s) of contract. In addition, the letter of intent should briefly indicate the offerors qualifications for participating in the development of an UWB FOPEN antenna. Letters of interest submitted by FAX, regular mail, or express delivery services are preferred. (088)
