摘要

本文论述了提高数字无线电通信系统隐身性能的必要性。综述了OFDM调制通信系统的功能原理、优点及应用领域。分析了OFDM调制信号在隐身指挥无线网络中应用的可能性。为此，在伪相空间中模拟ofdm信号的“形状”，直观评价其结构接近规则过程。利用北斗统计量对ofdm调制系统的隐身性能进行了估计，并与“白”噪声进行了比较。提出了利用混沌处理和混沌序列提高OFDM信号隐身性的方法。在总结部分，明确了进一步研究的方向。

Stealth Evaluation of the OFDM Communication System

The necessity of increase the stealth of the digital radio communication systems is showed in the paper. Functional principles, advantages and application fields of communication systems with OFDM modulation are reviewed. The possibilities of using application of signals with OFDM modulation in the stealthy command radio network is also analyzed. For this purpose, simulated the “shape” of the OFDM-signal in pseudo-phase space and visually evaluated that its structure is close to regular processes. The stealth of the systems with OFDM-modulation using BDS-statistic in comparison with “white” noise is estimated. The ways to increase the stealth of OFDM signals by using chaotic processes and sequences are proposed. At the summary are defined the directions of further researches.
