| 摘 要： | 在对直扩信号能够被检测截获的原因进行深入分析的基础上,针对现有各种直扩信号盲检测截获方法的关键所在,提出通过对直扩信号进行加扰和改变扩频码码速相结合的方法来改变其时域统计特性及其频域、谱相关域特征增强其通信隐蔽性的思想方法,并对经过处理后的直扩信号的特性进行了模拟探讨分析。

| Abstract: | Based on deep analysis of the reasons of the DSSS signals which can be detected and intercepted,in terms of various blind detecting and incepting methods for existing DSSS signals,the idea which changes time domain statistical characteristics and frequency domain and spectrum related domain characteristics to improve communication invisibility by the combination of scrambling of DSSS signals and changing spread spectrum code rate is presented,and the processed DSSS signal characteristics are simulated and analyzed. |
