DEVELOPMENT AND CONSTRUCTION OF A SELF-FOCUSING ANTENNA ARRAY SYSTEM.
Abstract
The construction and development of a high frequency (22.725 Mc) model of a self-focusing antenna array is described. Using this high frequency model, preliminary measurements were performed to measure the system acquisition, system phase jitter after acquisition, and the system's direction-finding capability. Theoretical analyses of the acquisition time, the phase jitter and signal summing were performed and presented. The results of these analyses are compared, where possible, with the experimental results. Preliminary analyses of the system's direction finding capability have also been performed and presented. The system is capable of resolving more than one source at any one time; that is, the system has a multi-source and/or multi-path discrimination capability. Some preliminary considerations are given to means whereby the direction to the various sources can be presented in real time, or after a short time delay. System block diagrams and schematic are presented and the circuits are described and discussed. (Author)
