Standard Avionics Modules (SAM) for Existing Modems.

Abstract

The objective of this project was to demonstrate the feasibility and cost effectiveness of applying the Standard Avionic Modules concept to communication/navigation ECCM modems. To make the project more tractable and more relevent, two L-band com/nav systems and a general PN PSK modem were considered. The two com/nav systems were JTIDS and GPS, and the PN PSK modem was an AJ modem using PN spreading and was capable of a data rate of 38.4 KBPS. A performance analysis resulted in a set of composite performance requirements. Signal processing functions were defined which would satisfy the performance requirements. With the performance requirements and signal processing functions several architectures were analyzed and partitioning of the modem function was undertaken. The final configuration of the modem was directly dependent upon the physical packaging technique adapted. The Navy SHP approach was compared to the Air Force ATR standard, specifically the 1/2 ATR standard and was discarded because of several deficiencies.
