Anti-Interference Strategies Review of Unified Spread Spectrum Telemetry Tracking and Control System

Z. Wu, N. Zhao, G. Ren and T. Quan

In this study, the advanced unified spread spectrum Telemetry Tracking and Control (TT and C) system (USSTTCS) in aerospace industry is introduced and the anti-interference strategies of it are reviewed. In USSTTCS, the inherent ranging ability of pseudo-noise code and the speciality of spread spectrum modulation make the complete unification realized, including measurement of range, velocity and angle as well as telemetry, telecontrol and communication functions. With Code Division Multiple Access (CDMA) system applied, the signal and equipment of multi-target or multi-station TT and C can be unified easily in USSTTCS. In USSTTCS, there are several kinds of interference, including narrowband interference, multiple access interference, multipath interference and near-far effect and there kinds of interference affect the performance of USSTTCS greatly. In this study, several kinds of interference in USSTTCS are introduced and then the strategies which can mitigate these kinds of interference in the USSTTCS are reviewed with their performance analyzed.
