摘要
运用SPWVD对脉内频率编码信号进行检测与参数估计,根据SPWVD的真边缘性实现了对频率编码信号的识别、突变点的检测以及瞬时频率的估计。该算法在低信噪比下,可以准确地提取出信号的脉内调制特征,有较好的应用价值。
SPWVD is used to detect and estimate the frequency coding pulse signal（FCP） and its pa- rameters. According to the edge property of the SPWVD, FCP recognition, trip point detection and the instantaneous frequency estimation is implemented. Pulse modulation characteristics can be extracted in low SNR using the algorithm which can be well applied.
