The objective of Phase I of the study is to define a wide range of alternative Communication, Navigation and Identification (CNI) architectures, to develop an approach for economic comparison of architectures, to establish criteria for selecting among the alternatives based on a set of requirements furnished by the government and to recommend a specific approach or approaches to be detailed further in the second phase of the study. The first step in performing the study consisted of reviewing and analyzing the results of previous studies related to CNI integration. This analysis in combination with information and direction from AFAL resulted in an assessment degree of time-sharing and pulse interleaving possible for the MFBARS resources such as antennas, transmitter power amplifier, IF amplifiers and signal processor channels. It also resulted in the establishment of a set of guidelines and ground rules that were used in the performance of the rest of the study tasks. Next several different overall architectures were developed. One of these architectures was a totally non-integrated configuration consisting of a set of separate equipment units, one for each CNI function (HF, VHF AM, VHF FM, UHF, JTIDS, IFF, TACAN, GPS, etc.). The units were assumed to be a next generation development beyond the current developed version of the equivalent unit. 收起
