Can I ask what kind of use cases would a spectrogram have for radar data? I've been messing around with making my own spectrogram app as well (linux desktop app and not web app though) and would be stoked to know if there's any potentially easy to reach use cases for it

Radar signals are modulated in very specific ways, which are visible right away even with plenty of noise on a spectrogram. Classifying the modulation of radar signals is something common in military contexts, since it allows you to listen for emissions and be able to tell if it's an enemy or an ally. I bet it has more uses than that, but it's the first one I could think of.
