Intrapulse Analysis of Complex Signals using IFM Receiver
Henryk Gruchalla, Mirosław Czyżewski, Adam Slowik · 2006
The multichannel IFM system capabilities for the internal structure analysis of the complex signals have been presented in the paper. Time analysis was used to obtain instantaneous phase for LFM, PSK and FSK signals. Some phenomena have the place for complex signals receiving using IFM systems. For the LFM and FSK signals instantaneous frequency estimation this phenomena have disadvantageous character, but for PSK signal case this effects are helpful for bit code recognition. To estimate the instantaneous frequency for few type complex signals the time analysis for one channel of microwave frequency discriminator have been done. The results of the analysis have been presented, too.
