Abstract

This document has been prepared to describe a high level technical concept of operations for a multifunctional system supporting both communications and surveillance applications. For illustrative purposes, the application is focused on an implementation with the small unit operations situational awareness system (SUOSAS) network and a generic software programmable radio. This CONOP includes a preliminary view of the network configuration, and the timesharing between communications and surveillance functions. In a typical push-to-talk voice radio, multiple radio elements share a single channel. Normally, each radio is employed as a communication device only a small percentage of the time. During the time that the radio is not being used for communication, it is available to support other functions. If the receive path of the radio is configured to scan the RF environment during these times, signals that are of interest to the radio user can be detected and analyzed. In addition, low cost time bases derived from global positioning system (GPS) clocks, provide the capability to determine the position of these signals based on time difference of arrival (TDOA) techniques. A software defined multiband radio, access to a common timebase, and a robust data network are required to support the functions described in the paper.
