摘要
在研究了JTIDS信号特点和扩频信号检测技术的基础上,分别对空间互谱检测法、二次功率谱检测法和平方倍频检测法进行了理论分析,通过Matlab仿真,给出了JTIDS的时域和频域波形,并比较了三种方法对JTIDS信号的检测性能,得出了平方倍频检测法更适合JTIDS信号的检测的结论。
Based on the study of signal characteristics of JTIDS and detection technology of spread spectrum signals, this paper makes analysis of space cross spectral detection, square multiple frequency detection, second power spectrum detection, The time and frequency wave of JTIDS are present by Matlab software. And JTIDS signal detecting results of three kinds of detecting arithmetic are verified, square multiple frequency detection way are more suited for JTIDS signal.
