Design of Ranging Code and Frequency-Hopping Sequence for DS/FH Hybrid TT&C System.

Abstract: A frequency-hopping sequence based on chaotic code is designed to solve the anti-interception and anti-jamming problems of TT&C system. It is generated by an improved binary quantization-based method and ranging long code is designed according to equivalent speed/multiple periods coding method. The results of numerical analysis indicate that hybrid spread spectrum TT&C system has made great progress in terms of anti-jamming and anti-interception performance compared with the current single spread spectrum.
