Joint tactical anti-jam communications: a systems approach.

Abstract

This study analyzes the conceptual design of a joint tactical anti-jam communication link from a systems point of view. It addresses the requirements and the specifications for a communication system providing an integrated solution for navies operating in closed-sea areas under intense enemy jamming activity. The concept of the proposed system is based on spread spectrum technology and on the Joint Tactical Information Distribution System (JTIDS). Spread spectrum technology has been an area of extensive research for many years. Satisfactory practical solutions have been provided through the implementation of several frequency hopping systems that give partial answer to the anti-jam (AJ) problem. JTIDS is the only hybrid spread spectrum system intended to provide a catholic answer. The AJ performance of the proposed system is examined theoretically under realistic scenarios. System feasibility, from the overall cost standpoint, is evaluated using life cycle costing and sensitivity analysis. The trade-off between the procurement of an original system and a JTIDS-based design is also evaluated, based on the possible research costs. It is assumed that acquisition or procurement of such a system is not limited by any technology transfer barriers.
