Azimuth Data Recorder-Reproducer Set AN/FSH-1 (XB-1)
Abstract
The research, design, development, and fabrication of Azimuth Data Recorder-Reproducer Set AN/FSH-1 (XB-1) are described. This is a shore-based equipment designed to record and reproduce bearing information from direction finders employing synchronous-motor driven goniometers. The equipment is intended to improve the accuracy of reported bearings and to increase signal capture probability, especially for flash transmission, by allowing an operator to observe repeated reproduction of the recorded d-f signal while adjusting the playback gain for optimum bearing determination. Magnetic recording on gear driven drums is utilized in conjunction with a frequency-modulated carrier system. Characteristics of the AN/FSH-1 (XB-1) equipment are presented in detail and the results of a 2000-hour life test are described. The recorder-reproducer fulfills all performance requirements set forth in the original problem request.
