Abstract

The objective of this study will be the exploitation of newly developed analytical concepts and algortihms for the design, development and software implementaton of a frequency hopping identification system. The hop identification capability of the system will be achieved by identifying the binary code being used by the hostile target. These identification techniques make use of real time measurements by the monitor of the times of arrival of relatively few transmissions of a single frequency among themany over which the target radio hops.The successful implementation of these techniques will allow the monitor to identify, track, demodulate or disrupt the frequency hopping communications link by constructing a frequency hopper which is equivalent to and synchronized to the one whose frequency hopping pattern is being observed. It is anticipated that the results of this program will lead to the development of a system which will be an effective complement to the current suite of US Airforce Electronic Countermeasure tools.
