Abstract :
The capabilities of a multichannel IFM system for instantaneous frequency measurement of complex pulse signals are presented. The frequency characteristics of the IFM systems are correct for CW and long pulse signals. For complex short pulse signals with a wide spectrum, the IFM´s frequency characteristics can be changed depending on the signal structure. Pulse signals with LFM (linear frequency modulation), NLFM (nonlinear frequency modulation) and FSK (frequency shift keying) have been used for the analysis. The results for time-domain and frequency-domain analysis methods are presented.
