Background Monitor for the SATCOM Signal Analyzer

摘要

A SATCOM Signal Analyzer (SSA) is being developed by the Satellite Communications Laboratory of the Naval Postgraduate School. The purpose of this system is to provide high-speed multi-channel digital spectrum analysis and characterization of the outputs of UHF communication satellite transponders while in orbit and operating. A Digital Computer Subsystem provides the control for most of the equipment in the system. The thesis documents a portion of the software development for this subsystem. This software performs all operator interaction using a Touch Input System and a Graphics Display. It is controlled to a large extent by menu data stored in a disc file, which can easily be extended or modified. Non-trivial file management and concurrent processing of several functions are major characteristics of this software. (Author)
