Characterization of anti-jamming effect on the Joint Tactical Information Distribution System (JTIDS) operating in complicated electromagnetic environment

Study of anti-jamming effects on the Joint Tactical Information Distribution System (JTIDS) operating in the complicated electromagnetic environment is carried out in this paper. With the help of Simulink simulation platform of MATLAB, the JTIDS model is built up using channel coding, spread spectrum and modulation technologies. It is shown that, with some interferences introduced into the system, its performance can be degraded seriously, however, the transmitted information, in some cases, can be restored at the receiver. Our simulated results could useful for the JTIDS design for anti-jamming.
