摘要
讨论了相位编码信号的时域微特征、频域微特征,分别研究了基于求平方的相位编码信号识别方法、基于时频曲线的相位编码信号识别方法、基于时相曲线的相位编码信号识别方法。通过测试与分析对比了3种识别方法各自的优劣。
This paper discusses the time domain micro-characteristic and frequency domain microcharacteristic of phase-coding signal,respectively studies the recognition methods of phase-coding signal based on quadratic pursuit,time-frequency curve and time-phase curve,compares the advantages and disadvantages of three recognition methods through test and analysis.
