Plot Spectrogram Using Radar Waveform Analyzer App

The radarWaveformAnalyzer is a Matlab™ App that lets you explore important properties of a signal such as its waveform, spectrum, and ambiguity function.

Open radarWaveformAnalyzer App

When you type radarWaveformAnalyzer from the command line or select the app from the App Toolstrip, an interactive window opens. The default window shows a rectangular waveform. You can then select various options to analyze different waveforms.

radarWaveformAnalyzer

Show the spectrogram of baseband FMCW signal

As an example, use the app to show the spectrogram of a continuous FMCW waveform.

  1. Set the Waveform to FMCW

  2. Set the Sweep Interval to Symmetric

  3. Set the Number of Sweeps to 4

  4. Set the View to Spectrogram

Then, you will see a plot of the spectrogram of the signal similar to this.
