| 摘 要： | 以单载频、线性调频、BPSK和FSK信号为例,通过提取信号的瞬时相位,对雷达信号的脉内调制特征进行了分析。首先介绍了信号瞬时相位的提取方法,然后通过瞬时相位微商得到信号的瞬时频率,接着引出了一种基于最小二乘算法的调制类型识别方法,最后对这种方法进行了仿真分析。仿真表明,相位测频法是一种有效的雷达信号调制特征分析工具。 |

| Abstract: | Through extracting signal instantaneous phase,sev er al kinds of intra-pulse modulation signatures of radar signal are analyzed and illustrated with single carrier frequency signal,linear frequency modulation si gnal,BPSK signal and FSK signal.At first,a method for extracting signal instanta neous phase is introduced.And then,signal instantaneous frequency is calculated by differentiating instantaneous phase.An approach to recognize modulation type based on Least Square algorithm is presented.At last,this method is simulated an d analyzed.According to the simulation results,measuring frequency through inst antaneous phase is an effective method for analyzing intra-pulse modulation sig natures of radar signals. |
| Keywords: | instantaneous phase instantaneous frequency Least Squ are algorithm intra-pulse modulation signature |
