Abstract : This report summarizes the work done to design, develop, fabricate, and test an experimental model Hgih Performance Electronically Modulated TACAN Antenna. The program objective was to demonstrate the feasibility of the technique and this was successfully achieved. The antenna system consists of two subsystems: The electronically modulated cylindrical array (AT-100) developed by Rantec, and the electronic generator furnished by the Air Force. The program consisted of two phases: (1) design and development of the antenna configuration, and (2) fabrication and test of the experimental model system. The results of the first phase, which established that the engineering design would result in successful performance, are documented in the Design Plan (July 1971). This report begins with a resume of the Design Plan including a description of the antenna system, its components, and discussion of the important design considerations. Results of the Performance Test Program are also presented and discussed. Measurements were made of all the performance characteristics required by the Statement of Work. A new reliability and maintainability analysis is included which formally confirms the outstanding life-cycle cost-savings obtained from the Electronically Modulated TACAN Antenna. Conclusions, based on the Program results, establish a set of tasks for continuing effort to achieve the next major developmental step, prototype antenna systems. (Author)
