DWT on short signals I have signals with a very short rate of ~100e-6 seconds, sampled at 10MHz,so about 1k samples.
I am wondering, is there a practical limit to the usefulness of time-frequency methods concerning a minimal duration of the signal or a certain sampling frequency for that matter?
i am talking about chirp radar signals which fires 1000 linear chirps each 100us long which I sample at 10 MHz. so the whole frame takes only about 100ms
With such short (known) stimuli, does it make sense to use generic analysis methods, or is it «better» (less work, results that are more usable) to tailor your processing to the transmitted processing (matched filter?) or apply a parametric model and some numerical optimization?
